- Modulation of Microbiota and its Impact on Depression
Authors: Kousik Maparu*
Abstract: Gut microbial flora is the largest micro-ecosystem in the human body, it is symbiotically associated with the host; and maintains normal physiological processes in a dynamic equilibrium state. A plethora of evidence supports that gut microbial flora influences the neurotransmitters of the central nervous system. This gut flora influences cognitive function, anxiety, depression; and mood disorders as they are capable of synthesizing neurotransmitters in the nervous system. Therefore intake of probiotics influences gut microbiome; and depression. The versatility and number of gut microbial flora varies individually, so the content of common gut microbes may affect the neurotransmitters, manipulating the gut microbiota with probiotics offers a novel approach to treat brain disorders such as depression via GUT-BRAIN AXIS. The present review outlines the aspect of such alterations and how modulation of gut microbiota influences depression.

- Beta-1 Receptor (β1) in the Heart Specific Indicate to
Stereoselectivity
Authors: Rezk Rezk Ayyad*; Ahmed Mohamed Mansour, Ahmed Mohamed Nejm, Yasser Abdel Allem Hassan, Norhan Hassan Gabr, Ahmed Rezk Ayyad
Abstract: The β1 receptor is one of the three beta receptors present in the human body, namely β1, β2, and β3. The β1 receptor is predominantly located in the heart, where it plays a crucial role in regulating the heart rate and the force of contraction, thereby increasing the cardiac output and the efficiency of blood pumping throughout the body. This receptor is targeted by a variety of pharmaceutical agents known as beta-blockers, which are commonly used in the treatment of cardiovascular conditions such as hypertension, angina, and arrhythmias.The β1 receptor exhibits stereoselectivity, meaning that different enantiomers (chiral molecules) of beta blockers can have varying levels of effectiveness and side effects. This study focuses on the stereoselectivity of the β1 receptor and the clinical implications of this property. It includes an examination of various β1 blockers, such as propranolol (a non-selective beta blocker), and selective β1 blockers like atenolol, bisoprolol, nebivolol, metoprolol, esmolol, acebutolol, and betaxolol. Each of these drugs has a unique chemical structure, with specific functional groups that contribute to their selective action on the β1 receptor.Furthermore, the β2 receptor, which is mainly present in the bronchi and bronchioles, is responsible for bronchodilation, and the β3 receptor, found in the bladder, helps reduce urinary urgency. Understanding the distinct locations and functions of these receptors allows for the development of targeted therapies with minimal off-target effects.This review highlights the importance of stereoselectivity in the development and use of β1 blockers, discussing their chemical structures, pharmacological activities, and therapeutic uses. It also explores the potential for future research and development of more selective and effective β1 receptor agonists and antagonists, which could offer improved therapeutic outcomes for patients with cardiovascular diseases.This study underscores the significant role of the β1 receptor in cardiovascular health and provides insights into the ongoing advancements in beta-blocker therapy. By delving into the stereoselectivity and specific actions of these drugs, the research aims to enhance the understanding and optimization of β1 receptor-targeted treatments in clinical practice.

- Experiences of Consumers on the Health Effects of Fake and Adulterated
Medicines in Nigeria
Authors: Chijioke M Ofomata; Nkiru N Ezeama, Chinelo Ezejiogu*
Abstract: Medicines are used to cure and treat ailments, relieve or eliminate disease symptoms, and slow down the disease process. Any attempt to disrupt this natural medicine process, using falsified medications, spells doom to a consumer of such medication. The challenge of fake medicines is a global one and affects developing and developed nations and currently assumes great significance as a result of globalization challenges, which have flattened the entire world, hence removing barriers to the movement of products and services. The cross-sectional survey was conducted, using six local government areas of Anambra State in South-East Nigeria, namely Awka, Nnewi, Onitsha, Aguata, Ogbaru, and Anaocha, among adults aged 18 years and above. A minimum sample size of 500 was calculated and stratified sampling was employed to select respondents in order to ensure that various population groups, the upper class, middle class, and lower class were represented.This research has shown that falsified medicine is an evil wind that blows nobody any good. It negatively affects every aspect of the citizen’s livelihood, ranging from their health, which manifests as treatment failures, deformities, loss of life to death, to loss of confidence in the healthcare providers, revenue losses to individuals, healthcare providers, manufacturers, and finally corruption of the genuine medicines supply chain with fake and adulterated medicines.The study has clearly shown the experiences of residents of Anambra State, South-East Nigeria with fake and adulterated medicines and also services as a wake-up call to medicines regulators like NAFDAC, PCN, the PSN, and Federal Ministry of Health to declare a state of emergency on the fight against fake and adulterated medicines and make enabling laws that are punitive enough towards the fight against this scourge, so that the healthcare and well-being of Nigerians would be assured at all times.

- Tussilago farfara Extracts Decrease Lung Injury in Fine Dust-Induced Mice
by Inhibiting of Inflammatory Cytokine Levels, Neutrophil Accumulation,
and Endothelial Dysfunction
Authors: Mi-Young Yun; Won-Jin Baek, Hwa-Jung Choi*
Abstract: Fine Dust (FD) in the respiratory air generates a variety of human disease issues throughout the earth. This study aimed to investigate whether (1) Tussilago farfara extracts (TF) decrease neutrophils accumulation, typical pathological features, and goblet cell hyperplasia in mice following exposure to fine dust (FD); (2) inflammatory cytokines result from FD exposure; and (3) asymmetric dimethyl-arginine (ADMA) and symmetric dimethyl-arginine (SDMA) levels in the mice following exposure to FD. Seven-week-old male Balb/c mice (n = 5/group) were instilled two times by intra-nasal-trachea (INT) injection for 3 days and 6 days to the mice four groups; normal, control, FD + dexamethasone (Dexa, positive control), and FD + TF groups. TF suspended in 0.5% carboxymethyl cellulose (CMC) was administered orally to the mice daily for 10 days (100 mg/kg). Neutrophil accumulation, typical pathological features, goblet cell hyperplasia, ADMA, and SDMA levels were assessed on day 10 in FD-induced mice. Results indicated FD significantly reduced neutrophil accumulation in BALF, typical pathological features containing goblet cell hyperplasia in lung tissues, and inflammatory cytokines [interleukin (IL)-17 and tumor necrosis factor-α (TNF-α), macrophage inflammatory protein-2 (MIP-2) and C-X-C motif chemokine 1 (CXCL-1)]. Furthermore, TF significantly decreased levels of elevated ADMA and SDMA by FD exposure. Collectively, TF decreased the counts of neutrophils in BALF, histological changes in lung tissues due to downstream secretion of inflammatory cytokines, and levels of ADMA and SDMA. Therefore, TF may be a potential therapeutics for treating FD-associated diseases.

- The Effect of Variable Doses of Imipramine and Amitriptyline on Learning
and Memory
Authors: Asuquo JO; Oyama SE, Seriki A Samuel*
Abstract: This study compares the effect of imipramine and amitriptyline on learning and memory. Thirty-five (35) healthy Swiss white (CD1) mice of both sexes weighing 18 g - 30 g were randomly divided into 5 groups (n = 7). Mice in group 1 (control) were administered 0.9% normal saline orally, while mice in groups 2 and 3 were treated with low (1.8 mg/kg) and high (3.7 mg/kg) doses of imipramine, groups 4 and 5 were treated with low (1.8 mg/kg) and high (3.7 mg/kg) of amitriptyline respectively. Treatment was for 21 days before tests. All animals were tested using the Morris Water Maze (MWM) and Novel Object Recognition Task (NORT) to assess visuospatial learning and memory as well as cognitive learning and memory. The results obtained from the Morris Water Maze during the acquisition training showed that the swim latencies were significantly lower (p < 0.05) in the amitriptyline low-dose group compared to the control group. During the reversal training, the swim latencies were significantly lower (p < 0.05) in the test groups compared to the control group. The result for the retention quadrant in the probe trials showed a significant decrease (p < 0.05) in the northeast quadrant in the test groups compared to the control group, with no significant difference in the visible platform day of the Morris Water Maze in the test groups compared to the control group. In the novel object recognition task, the short-term index of habituation was significantly lower (p < 0.05) in the low-dose imipramine and low-dose amitriptyline compared to the control group, the results also showed a significant increase (p < 0.05) in amitriptyline high dose group compared to imipramine and amitriptyline low dose group and the control group. The index of discrimination showed no significant difference among all groups. The long-term index of habituation and discrimination in the memory test showed a significant decrease (p < 0.05) in all the test groups compared to the control group. The results suggest that imipramine and amitriptyline impaired cognitive memory and enhanced visuospatial learning and memory functions.

- Benefits of using SLGT2 Inhibitors for Patients with CDK and DM2 to Reduce
Mortality Risks
Authors: Pandora Eloa Oliveira Fonseca; Jeremias Aguiar Azevedo, Sara Maria Gomes Bié, Sávio Benvindo Ferreira*
Abstract: Type 2 diabetes mellitus (T2DM) is the most common cause of chronic kidney disease (CKD). CKD is characterized by progressive liver tissue damage and is an important risk factor for mortality due to renal and cardiovascular outcomes. Thus, randomized clinical trials have investigated the use of sodium-glucose cotransporter 2 (SLGT2) inhibitors as a promising therapy for patients with CKD and T2DM. This study aimed to analyze the benefits of using SGLT2 inhibitors in patients with CKD and T2DM to reduce mortality risks. To this end, a qualitative, descriptive methodological approach was adopted using a literature review in the PubMed, Embase, and VHL databases. The inclusion criteria were clinical trial articles, randomized or non-randomized, cohort studies, case-control studies, and open access, published in Portuguese and English, between 2018 and 2023 with topics associated with SGLT2 inhibitors, CDK, and T2DM patients. In this context, it was observed that the risk of death from CKD in patients treated with Canaglifozin was 30% lower than in those treated with a placebo and that Dapaglifozin prolonged survival. In this context, when assessing the progression of kidney disease or death from cardiovascular causes in patients taking Empagliflozin, only 13.1% achieved the outcome compared to 16.9% on placebo, so the drug safely reduces the risk of mortality. Consequently, SGLT2 inhibitors have shown excellent results in the treatment of CDK and T2DM, with a reduction in the risk of mortality, positive effects on reducing renal and cardiovascular outcomes, as well as prolonging survival.

- Toxicity and Phytochemical Analysis of Five Medicinal Plants
Authors: Johnson-Ajinwo Okiemute Rosa*; Nyodee, Dummene Godwin
Abstract: Recent studies have shown that long-term uses of herbs have been associated with a rise in morbidity and mortality rates. While most researches are focused on bioactivity investigations, the toxicity of many plants has not been reported. There is a paucity of data on the potential toxicity of the following plants: Harungana madagascariensis (HM), Pterocarpus osun (PO), Phoenix dactylifera (PD), Annona muricata (AM), and Rutidea parviflora (RP). To evaluate the toxicity of the above-mentioned plants; two tests were employed namely: The Brine shrimp lethality test (BSLT) and the Allium cepa test. A correlation between the oral acute toxicity assay in mice and the LC50 obtained from BSLT has been established. Allium cepa test measures the potential genotoxic effects of plant extracts exerted on the root meristem of A. cepa (onions). Plant extracts were administered in concentrations ranging from 100 to 2500 µg/ml to the A. cepa for 72 h to obtain their Mitotic Indices (MI) and EC50. Results of the MI at 2500 µg/ml for HM, PO, PD, AM, and RP were 3.75, 4.96, 5.96, 6.10, and 6.71 while 281.81, 398.11, 501.19, 630.96, and 707.9 µg/ml were obtained as the respective EC50 values. Furthermore, 10-1000 mcg/ml concentrations were administered in the BSLT and the obtained LC50 values were 116.3, 250, 581.5, 581.5, and 750 µg/ml. The toxicity result demonstrated that the five plants were moderately toxic, with RP exhibiting minimal toxicity values and thus potentially having a good safety profile. The phytochemical screening of these plants revealed the presence of some pharmacologically important classes of compounds that are abundant. Several bioactive and toxic compounds were identified in the GC-MS analysis for some of the plants.

- Antibacterial Screening of Lippia origanoides Essential Oil on
Gram-negative Bacteria
Authors: Rodrigo Marcelino Zacarias de Andrade; Bernardina de Paixão Santos, Roberson Matteus Fernandes Silva, Mateus Gonçalves Silva*, Igor de Sousa Oliveira, Sávio Benvindo Ferreira, Rafaelle Cavalcante Lira
Abstract: Essential oils (EO) are extracted from different plant species and can be present in different plant organs. Rosemary-pepper EO is composed of around 50% to 70% thymol, a phenolic compound proven to be active against fungi and bacteria. The active components present in these compounds can affect the vital functionality of bacterial cells, leading to protein denaturation and cell lysis. Therefore, the present study aims to evaluate in vitro the antibacterial potential of Lippia origanoides EO against gram-negative bacteria. This is an exploratory study, with a technical-experimental procedure, with a quantitative approach, carried out at the Federal University of Campina Grande. The strains used were Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 25933, and Escherichia coli ATCC 25922, using concentrations of 1024, 512, 256, and 128 μg/ml using the disc diffusion method in triplicate. After the incubation period, the formation of halos of bacterial growth inhibition was not observed. There are possible causes for the lack of antibacterial activity of the EO concerning the strains of gram-negative bacteria used in the study, including the possibility of not containing components with antibacterial properties in concentrations sufficient for the expected activity at the concentrations tested. Based on the results obtained, the Rosemary-Pepper EO (Lippia organoids) did not demonstrate antimicrobial activity against the gram-negative bacteria used in the study. Therefore, the development of new research with Lippia origanoides essential oil with gram-positive bacteria is suggested.

- Correlation of Inappropriate use of Ceftriaxone and Bacterial Resistance
in the Hospital Environment: Integrative Review
Authors: Larissa Furtado Abrantes; Joyce Lima de Sousa, Joel Messias Soares Ramos, Rafael Rodrigues Leite, Sávio Benvindo Ferreira*
Abstract: Introduction: Bacterial resistance is a threat to public health, as it is estimated that 37,000 people die due to hospital infections, most of them due to multidrug-resistant bacteria. In part, this resistance is due to the inappropriate use of antibiotics, with ceftriaxone being one of the most used. Therefore, this article aims to analyze the consequences of using ceftriaxone in the hospital environment. Methodology: This is an integrative qualitative review, following the PICO strategy, using the Embase, BVS, and Pubmed databases, with the guiding question being: “In patients admitted to a hospital environment (P), is ceftriaxone used appropriately (I) for the treatment of infections (CO)'” and the time frame from 2013 to 2023. Results: 272 articles were found in total, 46 obtained from the VHL, 62 from PubMed, and 164 from Embase. Of these, 66 were duplicates, leaving 206 works for title and summary reading. After reading, 79 were selected for full reading, with 7 articles ultimately being selected for the study. An average of 62.3% of inappropriate use was found, with the minimum value found being 19% and the maximum being 87.9%. The main reasons for this use were: indication, dose, frequency, and duration. Conclusion: From reading the articles, it is concluded that the inappropriate use of ceftriaxone is mainly due to: indication, dose, frequency, and duration of treatment. These elements must be monitored, as their inappropriate use increases the length of hospital stay and may be associated with the emergence of bacterial resistance.

- The Cortisol Connection: Weight Gain and Stress Hormones
Authors: Balvinder Singh; Neelesh Kumar Maurya*
Abstract: Weight gain can be good or bad for health. Benefits include increased health for overweight people, disease or surgical recovery, and more. Health concerns, joint and musculoskeletal disorders, respiratory issues, metabolic abnormalities, cardiovascular health, psychological impact, reduced mobility, digestive troubles, hormonal changes, and cancer risk are negative impacts. Weight gain outcomes depend on heredity, weight distribution, and health. Maintaining a healthy weight needs a balanced diet, regular exercise, and stress management. A doctor or nutritionist can offer personalized weight management advice. Stress chemicals like cortisol trigger weight gain. ACTH stimulates adrenal glands to release cortisol, which increases hunger, fat storage, insulin resistance, and muscle loss. Understanding how stress hormones like cortisol affect weight gain is vital to reducing chronic stress’s health risks. Stress reduction, a balanced diet, regular exercise, proper sleep, social support, and professional treatment can mitigate these outcomes. Ultimately, stress hormones like cortisol can cause weight gain, but a holistic strategy tackling physical and psychological stress can help people maintain a healthy weight.

- Evaluation of the Anti-inflammatory Activity of Equisetum arvense and
Baccharis trimera Fractions
Authors: Carolina Ferreira Vaz; Alan Fernandes Mariano, Júlia Amanda Rodrigues Fracasso, Marcus Vinicius Vieitas Ramos, Lucineia dos Santos, Herbert Júnior Dias*
Abstract: Inflammation is a natural response of the body to defend itself against potential threats and can be reduced through physical activity, proper nutrition, and the use of herbal medicines, which are medicinal plants. In the study, we aim to examine the anti-inflammatory effects of the volatile and ethanolic fractions of two commonly used medicinal plants, Equisetum arvense, and Baccharis trimera. The essential oils were obtained by hydrodistillation of the fresh leaves of the plants, while the ethanolic extracts were obtained using classical methodologies. All fractions were tested for anti-inflammatory activity, evaluating their ability to stabilize the red blood cell membrane and inhibit the spreading, and phagocytosis by macrophages, at concentrations varying from 200 to 600 µg mL-1. The results of the experiments suggest that the ethanolic fraction of B. trimera shows promising results compared to the positive controls. Our investigations thus contribute to the specialized literature on the use of herbal medicines around nutrition, providing guidance for future studies on these fractions.

- Acyclovir Induced Acute Kidney Injury: A Case Report
Authors: Ziauddin Mohammed*; Mariya Zoha Muskan, Megha Mohan Narayanan
Abstract: Herpes zoster ophthalmicus, commonly referred to as shingles, manifests as a painful skin rash affecting one or more dermatome distributions of the trigeminal nerve, which supplies sensory innervation to the eye and its surrounding structures. Acyclovir stands as the primary pharmacological intervention for the treatment of this condition. However, its administration is associated with a notable risk of adverse effects, with acute kidney injury being the most prevalent. Herein, we present a case report involving a 59-year-old female patient who developed acute kidney injury after the prescription of Acyclovir for the management of herpes zoster ophthalmicus. This case underscores the importance of vigilance regarding potential renal complications associated with Acyclovir therapy, particularly in susceptible patient populations.
