Abstract
Positron emission tomography (PET) is a powerful imaging technique for biomedical research, drug development and medical diagnosis. The power of PET lies in biochemically selective radiotracers, labelled with positron emitters like fluorine-18 image chemical processes in vivo. A rapid and remarkably efficient, unprecedented protocol to select between S-F and C-F bond formation based on activation of 1,1-difluoroethylene groups followed by selective oxidation or reduction is described. While transition metal mediated conditions can be employed, the reaction proceeds in high yield using unobjectionable chemical reagents amenable to routine radiotracer production. The latter bodes well for facile clinical translation of the method. The new technique affords radiotracers and the labelling reagent 2,2-difluoro-2-(fluoro-18F)ethyl 4-methylbenzenesulfonate ([18F]1b) in excellent yield. Following oxygenation of the reaction mixture with medical oxygen or air, sulfonyl fluorides are obtained as the primary product. The new protocol was employed in a proof of principle to develop a radiometric assay for quantitation of sulfonylation yield with sulfonyl fluoride reagents. With operational ease and mild conditions, the method bodes a high potential for radiolabelling of biomolecules, known enzyme inhibitors and other temperature-sensitive compounds.

Abstract
Abstract The current study was designed to check the anthelmintic activities of some local plants. Seeds of Amomum (A.) subulatum and Vitex (V.) negundo in different solvents were subjected to in vitro (adult motility assay; AMA and egg hatch assay; EHA) and in vivo (faecal egg count reduction test; FECRT) anthelmintic activity testing protocols using Haemonchus (H.) contortus as an experimental model. The results of AMA, EHA, and FECRT were statistically analysed through linear regression and Duncan multiple range test. In AMA test, at 50 mg mL-1 concentration, the percent mortality of H. contortus was higher in A. subulatum than V. negundo, whereas, in EHA test, A. subulatum was proven better ovicidal (LC50=14.2 µg mL-1) than V. negundo (LC50= 65.7405 µg mL-1). The FECRT also indicated the better efficacy of A. subulatum than V. negundo against natural infection of gastrointestinal (GI) parasites. The crude powder of plants used in this study showed 29.6% to 57.7% anthelmintic. The reduction rate was found higher for A. subulatum (3 g kg-1) as compared to V. negundo (7 g kg-1). Reagrding efficacy analysis of solvents used for plants extract, ethyl acetate and chloroform were found better in increasing ovicidal activity in adult worms (in vitro testing), whereas, the crude aqueous methanol was found better than the crude powders in in vivo testing. It will be beneficial to document the indigenous knowledge to standard scientific procedures for their validation. This study will help to motivate the farmers to make a better choice of cultivation of the indigenous plants because of their varying efficacies as an alternative preventive approach against the GI parasitic infections.

Abstract
The structure and function of the brain greatly rely on different signaling pathways. The wide variety of biological processes, including neurogenesis, axonal remodeling, the development and maintenance of pre- and postsynaptic terminals, and excitatory synaptic transmission, depends on combined actions of these molecular pathways. From that point of view, it is important to investigate signaling pathways and their crosstalk in order to better understand the formation of toxic proteins during neurodegeneration. With recent discoveries, it is established that the modulation of several pathological events in Alzheimer's disease (AD) due to the mammalian target of rapamycin (mTOR), Wnt signaling, 5'-adenosine monophosphate activated protein kinase (AMPK), peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α), and sirtuin 1 (Sirt1, silent mating-type information regulator 2 homologue 1) are central to the key findings. These include decreased amyloid formation and inflammation, mitochondrial dynamics control, and enhanced neural stability. This review intends to emphasize the importance of these signaling pathways, which collectively determine the fate of neurons in AD in several ways. This review will also focus on the role of novel synthetic and natural bioactive molecules in balancing the intricate crosstalk among different pathways in order to prolong the longevity of AD patients.

Abstract
Physical, emotional, and psychological symptoms are common among women in their reproductive years, particularly during their menstrual cycle's luteal phase and the week before their period. Approximately 5-8 percent of women suffer with premenstrual syndrome, with the majority of those suffering from premenstrual dysphoric disorder (PMDD). Because of the complexity and multifaceted nature of the aetiology, it is yet unknown. Premenstrual syndrome (PMS) is diagnosed entirely on the basis of signs and symptoms, with no particular diagnostic tests available to confirm the diagnosis. Only a small number of therapeutic modalities are backed by clinical data, yet there are many accessible. After providing a brief overview of the disease, the author goes on to discuss the various hypotheses as to why PMS occurs. With an emphasis on tailored treatment based on symptom profile, it examines the wide range of non-pharmacological and pharmaceutical methods that are accessible today.

Abstract
When a girl experiences her first period, she starts a new phase of her life and becomes biologically capable of becoming a mother and giving birth to a child. Girls' hypothalamus-pituitary-ovary axis reaches "axial maturity" during puberty, when they are between the ages of 8 and 13 years old. Secondary biological features, including as growth, body-shape changes in females, breast growth, hair growth on the vulva, and hair growth on the axillary pits, are often observed during this era. The first menstruation, or menarche, is also commonly observed during this time. During the menstrual cycle, a woman's ability to conceive and give birth is at the core of her reproductive life.

Abstract
Heterocyclic compounds are that type of substances that are deeply intertwined with biological processes. Heterocycles are found in about 90% of commercially available medicines. In medicinal chemistry, finding new synthetic molecules with drug-like characteristics is a regular problem, which triggered the development of pharmacological molecules, the majority of which are based on N-heterocyclic motifs. Among the heterocycles, the pyrrole scaffold is the most commonly found heterocycle in both natural and synthetic bioactive compounds. Pyrrole has a five-membered heterocyclic ring with a plethora of pharmacophores, resulting in a library of different lead compounds. Pyrrole derivatives are physiologically active heterocyclic compounds that can be used as scaffolds for antibacterial, antiviral, anticancer, antitubercular, anti-inflammatory, and as enzyme inhibitors. On account of its extensive pharmacological profile, pyrrole and its various synthetic derivatives have drawn much attention among researchers to explore it for the benefit of humankind. This review presents an overview of recent developments in the pyrrole derivatives against multiple therapeutic targets.

Abstract
Cancer involves the uncontrolled division of cells resulting in abnormal cell growth due to various gene mutations and is considered the second major cause of death. Due to drug resistance to current anticancer drugs, cancer incidence is rising, and seeking effective treatment is a major concern. Natural products are prospective to yield unique molecules, as nature is a leading source of various drug molecules due to plenty of pharmacologically active molecules. Thymoquinone, a bioactive constituent obtained from Nigella sativa L., has drawn considerable attention among researchers in recent years due to its anticancer potential involving various molecular targets, including initiation of apoptosis initiation, arrest of cell cycle and generation of ROS, besides targeting multiple kinases such as tyrosine kinase, MAPK, and Janus kinase. The current review summarizes the thymoquinone chemistry, sources and its anticancer potential involving various molecular targets.

Abstract
Triple-negative breast cancer (TNBC) is associated with an increased risk of early recurrence and distant metastasis, as well as the development of therapeutic resistance and poor prognosis. TNBC is characterized by a wide range of genetic, immunophenotypic, morphological, and clinical features. TNBC is coined to describe cancers that lack estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). As a result, hormonal or trastuzumab-based treatments are ineffective in TNBC patients. TNBCs are biologically aggressive, and despite some evidence that they respond to treatment better than other forms of breast cancer, the prognosis remains poor. This is attributed to a shorter disease-free interval in adjuvant and neoadjuvant settings, as well as a more aggressive metastatic course. TNBC has a lot of clinical ramifications. In terms of new treatment methods, TNBC has lagged behind other types of breast cancer. There are not many options for treating this form of breast cancer because it is progressive. Many effective treatments for most breast cancers block the growth-stimulating effects of ER, PR, and/or HER2, leaving TNBC with few choices. Finding new and effective treatment options for TNBC remains a critical clinical need. To develop more effective drugs, new experimental approaches must be tested in patients with TNBC.

Abstract
The rising prevalence of osteoarthritis (OA) in the general population has necessitated the development of novel treatment options. It is critical to recognize the joint as a separate entity participating in degenerative processes, as well as the multifaceted nature of OA. OA is incurable because there is currently no medication that can stop or reverse cartilage or bone loss. As this point of view has attracted attention, more research is being directed toward determining how the various joint components are impacted and how they contribute to OA pathogenesis. Over the next few years, several prospective therapies focusing on inflammation, cartilage metabolism, subchondral bone remodelling, cellular senescence, and the peripheral nociceptive pathway are predicted to transform the OA therapy landscape. Stem cell therapies and the use of various biomaterials to target articular cartilage (AC) and osteochondral tissues are now being investigated in considerable detail. Currently, laboratory-made cartilage tissues are on the verge of being used in clinical settings. This review focuses on the update of clinical prospects and management of osteoarthritis, as well as future possibilities for the treatment of OA. Osteoarthritis (OA) is a general term that incorporates several different joint diseases. The exact pathophysiology of OA remains unclear. OA is incurable because there is currently no medication that can stop or reverse cartilage or bone loss. Nonsteroidal anti-inflammatory drugs are the most frequently prescribed medications to alleviate arthritic discomfort. Stem cell therapies to target articular cartilage and osteochondral tissues are now under investigation.

Abstract
Polycystic ovarian syndrome (PCOS) is the most frequent endocrine disorder among women of reproductive age. Some of the indications and symptoms of PCOS include amenorrhoea, hirsutism, infertility, obesity, acne vulgaris and androgenic alopecia. PCOS is a crippling condition that affects a woman's identity, mental health and overall quality of life (QOL). In persons with PCOS, anxiety and sadness are assumed to be multifactorial. According to some specialists, physical symptoms like acne, hirsutism and obesity have been linked to psychiatric morbidities. Many aspects of it remain unknown, including its cause, progression throughout life, symptom spectrum and level of morbidity. PCOS is a complex disease that has an impact on many aspects of a person's health, including their mental health. Anxiety and depression are three times as common in PCOS patients as in non-PCOS people. Anxiety and depression symptoms are also more common and more intense in those with PCOS. There isn't enough research on the prevalence of anxiety and depression in patients with PCOS. It's unclear what causes persons with PCOS to be more anxious and depressed. It could be the result of PCOS symptoms, hormonal changes, or a combination of factors that are currently unclear. Our review article will help to highlight the most recent research on anxiety and depression in PCOS women.

Abstract
Less vascular resistance, higher vascular permeability and improved cardiac output include anatomical and physiological changes related to pregnancy. These are needed to accommodate an increase in plasma volume and ensure significant organ infusion. Nevertheless, increases in oestrogen levels may lead to an increase in the risk of coagulation and thrombosis. Increased levels of progesterone increase the risk of thrombosis due to vasodilation, vascular stasis and edoema in these situations. The increased resistance in preeclampsia maternal systemic blood arteries can create high blood pressure that can interfere with blood flow in numerous organs (including liver, kidneys, brain and placenta). The risk of issues such as pulmonary edoema, placental abruption, pneumonia of aspiration, renal failure, hepatic failure and stroke in pregnant women is increased by Preeclampsia and eclampsia. Some peripheral neuropathies (carpal tunnel syndrome, peripheral facial palsy) and central neurological conditions (seizure, migraine, stroke, epilepsy) may become more common during pregnancy because of the exacerbation of the pre-existing neurologic condition or the onset of neurological disturbance caused by pregnancy physiological changes (such as headache or vascular disorders). During the three trimesters of pregnancy, neurological disorders are both peripheral and central. Therefore, an early and correct diagnosis is required to improve pregnancy care, treatment and perinatal outcomes. The aims of this paper are to identify, define and manage the most prevalent peripheral and centrally occurring neurological disorders in the pregnancy.

Abstract
Menstrual-related issues have significant public-health ramifications. Women who are having menstruation troubles should get their mental health checked by healthcare specialists. In young women, a menstrual-related condition has serious health implications. Young females who have menstrual issues miss job and school, and their behavioural and mental development suffers as a result. Depression and anxiety have an impact on women's menstrual periods in adults. Symptoms like as cramps, tiredness, backache, swelling abdomen, and painful breasts have also been described in women with menstrual misery. Menstrual distress has been shown to impair women's daily activities, as well as their reproductive and psychological health, according to research. Menstrual periods are frequently accompanied by a variety of unpleasant symptoms, such as premenstrual syndrome, which includes symptoms such as mild cramping and exhaustion. The severity of these symptoms, on the other hand, differs from woman to woman, depending on their health, food, way of life, and other factors. Women with menstrual-related issues have also reported smoking, alcohol intake, and an increase in hunger. Furthermore, young women experience emotional disturbances such as melancholy, restlessness, and despair. It is a sign of an atypical menstrual cycle if there is no cycle or if the bleeding is atypical or light. As a result, it is critical to maintain contact with a gynaecologist in order to detect any significant changes in a regular menstrual cycle.

Abstract
Polycystic ovarian syndrome is the most well-known endocrine condition among women of this generation (PCOS). Symptoms of hyperandrogenism, irregular menstrual periods, and insulin resistance are all traits associated with PCOS. In women with PCOS, the chance of having problems including infertility, insulin resistance, and type 2 diabetes increases. The PCOS board hopes to reduce body weight and insulin levels, restore fertility, control excessive hair growth on the body or scalp, re-establish the regular feminine cycle, and avoid misunderstandings. Insulin sensitizers have been one of the most common metabolic modulators, but their effectiveness has been sporadic. Insulin resistance, followed by thiazolidinediones, is central to the pathophysiology of PCOS, with metformin having nearly similar efficacy. In the management of PCOS, statins and incretins are newer therapies with obvious metabolic targets. Vitamin D, acarbose, and myoinositol are just a few of the reciprocal and optional clinical treatments that have been proved to be useful in the treatment of PCOS. The number of viable methods for dealing with PCOS-related infertility has increased as well. Despite the fact that clomiphene citrate (CC) has long been the gold standard for ovulation induction in the event of ovulatory infertility, aromatase inhibitors can induce ovulation with results that are nearly identical to or better than those reported with CC, aromatase inhibitors can cause ovulation with results that are nearly identical to or better than those reported with CC. Ovarian incitement conventions that intelligently utilize gonadotropins, gonadotropin-delivering hormone rivals, the approach of ovarian boring, and assisted conceptive advancements with in vitro oocyte development indicate an expanding level of therapeutic progress.

Abstract
Obesity has been identified mainly as a raise in the body's adiposity leading to prolonged overshoot of caloric intake over expenditure. Obesity has significant health-altering implications which have been shown to be implicated in the pathogenesis and progression of other diseases through its extensive physiological assaults. The prevalence of overweight and obesity has been an increasing epidemic worldwide. The number of obese births was even on the increase, with an increasing number of women of reproductive age registering as obese. Obesity is related to adverse perinatal outcomes and increased morbidity and mortality in pregnant women. The potential risk for multiple antenatal, postpartum, intrapartum, and neonatal complications is maternal obesity. Greater risk of developing Gestational Diabetes Mellitus (GDM), pregnancy induced hypertension (PIH), pre-eclampsia, risk of venous embolism, increased need for labor induction, and cesarean sections in the mother have been recorded in a comprehensive analysis of pregnancy complications associated with obesity. The link between obesity, gestational diabetes, and pregnancy outcomes will be briefly shown in this article.

Abstract
Background: An examination of drug use is done in a particular setting, searching for drug use that isn't fair. At the population level, the use of psychotropic drugs for mental illness can be an effective way of identifying and tracking the level of treatment for these conditions. They also provide information on ethical drug use, informed by the currently available information on a medication's benefits and risks.
Objective: A major objective of the research was to gather data on patterns of drug use in the psychiatry outpatient department of a tertiary care hospital in Srinagar, Jammu & Kashmir, India.
Methodology: The drug use research was performed in a tertiary care hospital in Srinagar, Kashmir, India, in a psychiatry outpatient clinic. This research was observational, cross_sectional, and open_ended in nature. All patients who attended the Psychiatry OPD and fulfilled the inclusion criteria over the course of a six_month cycle were included in the study.
Results: Over a period of six months, 600 patients from the psychiatry outpatient department of a tertiary care hospital in Srinagar, Jammu & Kashmir, India were assessed. All patients were classified into seven age groups: up to 14 years old (A), 15 to 25 years old (B), 26 to 35 years old (C), 36 to 45 years old (D), 46 to 55 years old (E), 56 to 65 years old (F), and over 65 years old (G). Clonazepam was the most commonly prescribed medication (152 cases), followed by olanzapine (132 cases), lorazepam (105 cases), and escitalopram (92 cases).
Conclusion: Measuring drug use in treatment centres not only explains drug use rates and prescribing behaviour, but it also helps in the identification of causes of polypharmacy and the problems associated with it. Making a habit of setting standards and gauging the quality of clinical treatment using performance feedback should become standard clinical protocol.

Abstract
Reproductive health is a broad concept that encompasses mortality, morbidity, and quality of life associated with the reproductive system, mechanism, and incidents encountered at all ages by men and women. Orthodox Indian society finds the conversation on reproductive health to be a taboo and discourages open conversations about it. Polycystic ovary syndrome (PCOS) is a reproductive-age metabolic endocrine disorder found in females. Females suffering from PCOS are prone to reproductive, metabolic, and cardiovascular disorders. In this paper, we will systematically review about effect of PCOS on Reproductive Health of Women. The numerous electronic databases such as: BMJ, LANCET, PUBMED, Unicef Website, WHO Website and Google Scholar have been comprehensively searched for studies linked to PCOS, its various effects and effect on women's reproductive health. For additional analyses, we have reviewed reference lists of reviews and collected papers. The effects of PCOS on women's reproductive health have been verified by several scientific reports worldwide. PCOS is a hormonal condition, as per multiple reports, with the ability to lead to different outcomes. It still appears to be a common cause among females of infertility. An integral aspect of the treatment of this disease is the early diagnosis of long-term morbidities by effective screening tests. In the future, studies must concentrate on the missing holes in our growing perception of this disease. Several studies have confirmed that reproductive morbidity, including irregular uterine bleeding, abortion, miscarriage, and other risk of pregnancy during reproductive years, is associated with PCOS. PCOS is an amalgam of physiological and psychosocial dysfunction, not just an endocrine disorder.

Abstract
A series of triazole-based compounds was synthesized using a click chemistry approach and evaluated for the inhibition of α-synuclein (α-syn) fibrillogenesis and its disaggregation. Compounds Tr3, Tr7, Tr12, Tr15, and Tr16 exhibited good effect in inhibiting α-syn fibrillogenesis confirmed by Thioflavin-T assay and fluorescence microscopy and α-syn disaggregation confirmed by fluorescence microscopy. Molecular docking was used to understand the plausible mechanism of the test compounds for inhibiting the α-syn fibrillogenesis and to verify the in vitro results. Compounds Tr3, Tr7, Tr12, Tr15 and Tr16 showed good binding interactions with the essential amino acid residues of α-syn. The compounds which were found to be good inhibitors or disaggregators had no toxic effects on the SH-SY5Y cell line. These compounds have the potential to be developed as therapeutic interventions against synucleinopathies including Parkinson's disease and Lewy body dementia.

Abstract
BACKGROUND Gall bladder cancer (GBC) is an aggressive cancer with specific predilection like female gender and specific geographical areas, however the molecular mechanisms and factors contributing to the clinical or biological behavior are not understood. AIM The aim of this study was to perform a comprehensive analysis of differentially expressed genes in advanced GBC and chronic cholecystitis (CC) cases. MATERIALS AND METHODS Microarray was planned on fresh specimens of advanced GBC and CC cases using single color cRNA based microarray technique (8X60K format; Agilent Technologies, USA). Twelve advanced GBC and four CC patients were included in the study. RESULTS Of the total of 1307 differentially expressed genes, 535 genes were significantly upregulated, while 772 genes were significantly downregulated in advanced GBC vs CC samples. Differentially expressed genes were associated with biological processes (55.03%), cellular components (31.48%), and molecular functions (13.49%) respectively. The important pathways or key processes affected were cell cycle, DNA replication, oxidative stress, gastric cancer pathway. Using in silico analysis tools, three differentially expressed genes i.e. TPX2, Cdc45 and MCM4 were selected (for their significant role in DNA replication and microtubule function) and were further validated in 20 advanced GBC cohort by immunohistochemistry. Significant positive association of Cdc45 and MCM4 proteins was found in advanced GBC cases (p = 0.043), suggesting the probable oncogenic role of Cdc45 and MCM4 proteins in advanced GBC. CONCLUSION Our data demonstrate the potential regulation of Cdc45-MCM4 axis in advanced GBC tumors. Additionally, our study also revealed a range of differentially expressed genes (e.g. TPX2, AKURA etc.) between GBC and CC, and further validation of these genes might provide a potential diagnostic or therapeutic target in future.

Abstract
Targeting Falcipain-2 (FP2) for the development of antimalarials is a promising and established concept in antimalarial drug discovery and development. FP2, a member of papain-family cysteine protease of the malaria parasite Plasmodium falciparum holds an important role in hemoglobin degradation pathway. A new series of quinoline carboxamide-based compounds was designed, synthesized and evaluated for antimalarial activity. We integrated molecular hybridization strategy with in-silico drug design to develop FP2 inhibitors. In-vitro results of FP2 inhibition by Qs17, Qs18, Qs20 and Qs21 were found to be in low micromolar range with IC50 4.78, 7.37, 2.14 and 2.64 µM, respectively. Among the 25 synthesized compounds, four compounds showed significant antimalarial activities. These compounds also depicted morphological and food-vacuole abnormalities much better than that of E-64, an established FP2 inhibitor. Overall these aromatic substituted quinoline carboxamides can serve as promising leads for the development of novel antimalarial agents.

Abstract
Parkinson's disease (PD), a calamitous neurodegenerative disorder with no cure till date, is closely allied with the misfolding and aggregation of α-Synuclein (α -Syn). Inhibition of α-Syn aggregation is one of the optimistic approaches for the treatment for PD. Here, we carried out hypothesis-driven studies towards synthesising a series of pyrazolo-pyridine carboxylate containing compounds (7a-7m) targeted at reducing deleterious α-Syn aggregation. The target compounds were synthesized through multi-step organic synthesis reactions. From docking studies, compounds 7b, 7g and 7i displayed better interaction with the key residues of α-Syn with values: -6.8, -8.9 and -7.2 Kcal/mol, respectively. In vivo transgenic C. elegans model of Synucleinopathy was used to evaluate the ability of the designed and synthesized compounds to inhibit α-Syn aggregation. These lead compounds 7b, 7g and 7i displayed 1.7, 2.4 and 1.5-fold inhibition of α-Syn with respect to the control. Further, the strategy of employing pyrazolo-pyridine-based compounds worked with success and these scaffolds could be further modified and validated for betterment of endpoints associated with PD.

Abstract
Reproductive health is a relatively new concept that recognizes that especially a young girl has special reproductive health needs before, during and beyond the childbearing age. It also lays emphasis on the fact that health (more importantly reproductive health) of the present generation has an everlasting effect on the overall health of the next generation and that both are of crucial importance for socio-economic development. Reproductive health need of young people especially for young girls and women includes needs for reproductive health care, family planning, HIV/AIDS information, safer sex, unwanted pregnancy, early pregnancy, sexually transmitted diseases (STDs), safe abortion and safe motherhood. Recently a number of programs for school going adolescent in India have focused on information, education, and communication with a limited focus on the provision of clinical and counseling services on reproductive health. Educational programs can increase awareness about reproductive health but this awareness may not always translate into appropriate help-seeking behavior by adolescents. The limited knowledge about reproductive health issues makes young girls vulnerable to various diseases and infections including HIV/AIDS/STDs, substance abuse, sexual violence, and exploitation. In this paper, we would briefly focus on various aspects of reproductive health.

Abstract
Polycystic Ovary Syndrome (PCOS) is the most common, yet complex, endocrine disorder affecting women in their reproductive years and is a leading cause of infertility. This disease appears to be multifactorial and polygenic in nature involving multisystem dysfunction, namely reproduction, endocrine and metabolic. Hyperandrogenism and insulin resistance appear to be central cause to the pathophysiology of the disease. The glucose and insulin metabolism pathways have been studied and debated to understand whether Insulin Resistance is due to a defect in insulin action or a primary defect in β-cell function or decreased hepatic clearance of insulin, or a combination of all these factors. Numerous studies have demonstrated that obese, normal weight and thin women with PCOS have a form of insulin resistance that is unique and intrinsic to the disorder. Moreover obese women with PCOS possess an additional burden of insulin resistance resulting from their excess adiposity. Hyperinsulinemia leads to increase in androgen production directly by acting as a co-gonadotropin, augmenting Luteinizing Hormone activity within the ovary, and indirectly by increasing serum LH pulse amplitude. Whereas Androgens may in turn contribute at least partially to the insulin resistance state linked with PCOS. In this review, we will briefly study the role of insulin resistance in polycystic ovary syndrome.
Keywords: Polycystic ovary syndrome, insulin resistance, Hyperandrogenism.

Abstract
Diabetes is a chronic endocrine disease with global prevalence and increasing incidence. Diabetes presents with a major health issue in all age groups in the present times owing to its multisystem involvement and serious complications. In spite of drug development and therapeutic interventions, successful treatment of diabetes still remains a challenge and worldwide research is focused on finding alternative modalities. By conducting sizable amount of analytical work, numerous traditional medicines have been found for diabetes. Substances and extracts isolated from completely different natural resources particularly plants have perpetually been a fashionable arsenal for dominant and treating polygenic disorders downside and complication arising because of it. Many medicinal plants have shown promising effects in experimental animals which can be extrapolated to humans also. In this paper, we will review various medicinal plants showing anti-diabetic activity in experimental animals.

Abstract
The antibacterial effect of ZnO nanoparticles is tested against Staphylococcus aureus, (a Gram-positive pathogenic bacterium) from a particle-size, concentration, and surface-defects point of view. Activation of antibacterial activity was achieved by standard well diffusion agar and minimum inhibitory concentration procedures. Our results show that smaller-sized particles are more effective inhibitors of bacterial activity when used in a certain optimum concentration. To reveal the underlying mechanism of the observed size and concentration-dependent bacterial activity inhibition, we measured the concentrations of Zn2+ ions released in each suspension by an inductive couple plasma optical emission spectrophotometer. Additionally, photoluminance spectra of our samples show significant surface defects (mainly oxygen vacancies) that generate reactive oxygen species. The underlying mechanism of the observed size- and concentration-dependent bacterial activity inhibition is attributed primarily to the release of Zn2+ ions and generation of reactive oxygen species that interact and penetrate the cell membrane, causing lethal damage to the cell. Finally, the antibacterial effectiveness and maximum sensitivity of our nanoparticles is confirmed by optical density measurements.

Abstract
In our endeavor towards the development of potent multitarget ligands for the treatment of Alzheimer's disease, a series of triazine-triazolopyrimidine hybrids were designed, synthesized and characterized by various spectral techniques. Docking and scoring techniques were used to design the inhibitors and to display their interaction with key residues of active site. Organic synthesis relied upon convergent synthetic routes were mono and di-substituted triazines were connected with triazolopyrimidine using piperazine as a linker. In total, seventeen compounds were synthesized in which the di-substituted triazine-triazolopyrimidine derivatives 9a-d showed better acetylcholinesterase (AChE) inhibitory activity than the corresponding tri-substituted triazine-triazolopyrimidine derivatives 10a-f. Out of the disubstituted triazine-triazolopyrimidine based compounds, 9a and 9b showed encouraging inhibitory activity on AChE with IC50 values 0.065 and 0.092 μM, respectively. Interestingly, 9a and 9b also demonstrated good inhibition selectivity towards AChE over BuChE by ∼28 folds. Furthermore, kinetic analysis and molecular modeling studies showed that 9a and 9b target both catalytic active site as well as peripheral anionic site of AChE. In addition, these derivatives effectively modulated Aβ self-aggregation as investigated through CD spectroscopy, ThT fluorescence assay and electron microscopy. Besides, these compounds exhibited potential antioxidants (2.15 and 2.91 trolox equivalent by ORAC assay) and metal chelating properties. In silico ADMET profiling highlighted that, these novel triazine derivatives have appropriate drug like properties and possess very low toxic effects in the primarily pharmacokinetic study. Overall, the multitarget profile exerted by these novel triazine molecules qualified them as potential anti-Alzheimer drug candidates in AD therapy.

Abstract
Mesenchymal stem cells (MSCs) derived from human umbilical cord (UC) have been considered as an important tool for treating various malignancies, tissue repair and organ regeneration. Umbilical cord-derived mesenchymal stem cells (UC-MSCs) are better alternative to MSCs that derived from bone marrow (BM-MSCs) as they are regarded as medical waste with little ethical concern for research and easily culture-expanded. In this present study, the foetal distal end of human UC was utilised to generate MSC by explant method. Upon in vitro culture, adherent cells with fibroblastic morphology were generated with rapid growth kinetics. Under the respective inductive conditions, these cells were capable of differentiating into adipocytes and osteocytes; express an array of standard MSC's surface markers CD29, CD73, CD90, CD106 and MHC-class I. Further assessment of immunosuppression activity revealed that MSCs generated from UC had profoundly inhibited the proliferation of mitogen-activated T lymphocytes in a dosedependent manner. The current laboratory findings have reinforced the application of explant method to generate UCMSCs thus, exploring an ideal platform to fulfil the increasing demand of MSCs for research and potential clinical use.

Abstract
Understanding and controlling structural properties of the materials are crucial in materials research. In this paper, we report that crystallinity and crystallographic orientation of Pd nanowires can be tailored by varying the fabrication conditions during electrochemical deposition in polycarbonate ion-track templates. By changing the deposition temperature during the fabrication process, the nanowires with both single- and poly-crystallinities were obtained. The wires with preferred crystallographic orientations along [111], [100], and [110] directions were achieved via adjusting the applied voltage and temperature during electrochemical deposition.

Abstract
Neurodegenerative diseases are among the most challenging diseases with poorly known mechanism of cause and paucity of complete cure. Out of all the neurodegenerative diseases, Alzheimer's disease is the most devastating and loosening of thinking and judging ability disease that occurs in the old age people. Many hypotheses came forth in order to explain its causes. In this review, we have enlightened Glycogen Synthase Kinase-3 which has been considered as a concrete cause for Alzheimer's disease. Plaques and Tangles (abnormal structures) are the basic suspects in damaging and killing of nerve cells wherein Glycogen Synthase Kinase-3 has a key role in the formation of these fatal accumulations. Various Glycogen Synthase Kinase-3 inhibitors have been reported to reduce the amount of amyloid-beta as well as the tau hyperphosphorylation in both neuronal and nonneuronal cells. Additionally, Glycogen Synthase Kinase-3 inhibitors have been reported to enhance the adult hippocampal neurogenesis in vivo as well as in vitro. Keeping the chemotype of the reported Glycogen Synthase Kinase-3 inhibitors in consideration, they may be grouped into natural inhibitors, inorganic metal ions, organo-synthetic, and peptide like inhibitors. On the basis of their mode of binding to the constituent enzyme, they may also be grouped as ATP, nonATP, and allosteric binding sites competitive inhibitors. ATP competitive inhibitors were known earlier inhibitors but they lack efficient selectivity. This led to find the new ways for the enzyme inhibition.

Abstract
AIMS To investigate the antifungal activity of conventional chitosan and chitosan-loaded nanoemulsions against anthracnose caused by Colletotrichum spp. isolated from different tropical fruits. METHODS AND RESULTS In vitro results illustrated that conventional chitosan onwards 1·5% concentration inhibited radial mycelial growth, conidial germination, sporulation and dry weight of mycelia for Colletotrichum musae (Berk. & Curt) Arx. isolated from banana, Colletotrichum gloeosporioides (Penz.) Penz and Sacc. isolated from papaya and dragon fruits. For further investigations, chitosan-loaded nanoemulsions were prepared, and chitosan at 2·0% concentration with 200 nm droplet size gave the best results in terms of all the in vitro parameters tested for C. musae and at the same concentration with 600 nm droplet size for both the isolates of C. gloeosporioides. However, the results obtained at 2·0% chitosan concentration with different droplet sizes were nonsignificantly different with 1·0 and 1·5% concentrations. Therefore, for in vivo studies, only 1·0% chitosan with different droplet sizes was used. In terms of fungicidal effects and maintaining postharvest quality of banana, papaya and dragon fruits, chitosan at 1·0% concentration with a droplet size of 200 nm in banana and 600 nm in papaya and dragon fruits showed the best results in delaying the onset of anthracnose and maintaining quality of all the fruits for up to 28 days of cold storage. CONCLUSION Chitosan used in a conventional form showed good results but not as effective as in the form of nanoemulsions. SIGNIFICANCE AND IMPACT OF THE STUDY The results of this study suggest that instead of applying chitosan in a conventional form, chitosan in the form of nanoemulsions could be more effective as a biofungicide for controlling anthracnose of fresh fruits. Moreover, it could be cost-effective as the amount of chemical used is reduced when applied in the form of nanoemulsions.

Abstract
Functional analysis of neutrophils requires isolation of these cells in the laboratory. Current isolation procedures are time consuming and can potentially activate the resting neutrophils. Thus, in this present study, we have optimised an existing laboratory protocol for human neutrophil isolation from peripheral blood. Twenty ml of blood samples were subjected to optimised density gradient separation and dextran sedimentation to obtain a pure population of neutrophils. The efficacy of the optimised manual post isolation of neutrophils was compared with pre isolation count performed by an automated haematology analyzer. The recovery of neutrophils via our optimised methods was 65.5% in comparison with neutrophils counts at pre-isolation. The morphological analysis of isolated neutrophils indicated the purity level more than 95% using Leishman staining. Our optimised laboratory procedures for neutrophils isolation successfully harvested neutrophils with good viability, purity and post recovery yield. This procedure provides an ideal platform to separate neutrophils for in vitro studies.

Abstract
Cobalt nanowires with controlled diameters have been synthesized using electrochemical deposition in etched ion-track polycarbonate membranes. Structural characterization of these nanowires with diameter 70, 90, 120 nm and length 30 μm was performed by scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray diffraction techniques. The as-prepared wires show uniform diameter along the whole length and X-ray diffraction analysis reveals that [002] texture of these wires become more pronounced as diameter is reduced. Magnetic characterization of the nanowires shows a clear difference of squareness and coercivity between parallel and perpendicular orientations of the wires with respect to the applied field direction. In case of parallel applied field, the coercivity has been found to be decreasing with increasing diameter of the wires while in perpendicular case; the coercivity observes lower values for larger diameter. The results are explained by taking into account the magnetocrystalline and shape anisotropies with respect to the applied field and domain transformation mechanism when single domain limit is surpassed.

Abstract
BACKGROUND AND PURPOSE Impaired cortical venous outflow and abnormal deep venous collaterals are common in Sturge-Weber syndrome (SWS), but their relation to brain metabolism and function is poorly understood. In this study, advanced MR imaging techniques, such as susceptibility-weighted imaging (SWI) and diffusion tensor imaging (DTI), were applied in conjunction with positron-emission tomography (PET), to assess cortical and white matter structural abnormalities and their relation to cortical glucose metabolism and cognitive functions in children with unilateral SWS. MATERIALS AND METHODS Thirteen children (age, 1.5-10.3 years) with unilateral SWS underwent MR imaging with SWI and DTI, glucose metabolism PET, and comprehensive neuropsychologic assessment prospectively. The MR imaging and PET images were coregistered and cortical regions showing decreased glucose metabolism were compared with locations of SWI signal intensity abnormalities, changes in white matter water diffusion, and cognitive functions. RESULTS SWI detected both cortical abnormalities (n=8) and deep transmedullary veins (n=9), including those in young children with no cortical SWI signal intensity changes. These veins were often located under cortex adjacent to hypometabolic regions. DTI showed abnormal water diffusion both under hypometabolic cortex and in adjacent white matter with collateral veins. Cognitive dysfunction was associated with abnormal water diffusion in the posterior white matter. CONCLUSIONS Transmedullary venous collaterals can be detected early by SWI and persist in white matter adjacent to damaged cortex in children with SWS. Microstructural white matter damage extends beyond cortical abnormalities and may contribute to cognitive impairment. SWI and DTI can be incorporated into clinical MR imaging acquisitions to objectively assess microstructural abnormalities at different stages of SWS.
