Abstract
Central nervous system disorders are prevalent, profoundly debilitating, and poorly managed. Developing innovative treatments for these conditions, including Alzheimer's disease, could significantly improve patients' quality of life and reduce the future economic burden on healthcare systems. However, groundbreaking drugs for central nervous system disorders have been scarce in recent years, highlighting the pressing need for advancements in this field. One significant challenge in the realm of nanotherapeutics is ensuring the precise delivery of drugs to their intended targets due to the complex nature of Alzheimer's disease. Although numerous therapeutic approaches for Alzheimer's have been explored, most drug candidates targeting amyloid-β have failed in clinical trials. Recent research has revealed that tau pathology can occur independently of amyloid-β and is closely correlated with the clinical progression of Alzheimer's symptoms. This discovery suggests that tau could be a promising therapeutic target. One viable approach to managing central nervous system disorders is the administration of nanoparticles to neurons, intending to inhibit tau aggregation by directly targeting p-tau. In Alzheimer's disease, beta-amyloid plaques and neurofibrillary tau tangles hinder neuron transmission and function. The disease also triggers persistent inflammation, compromises the blood-brain barrier, leads to brain shrinkage, and causes neuronal loss. While current medications primarily manage symptoms and slow cognitive decline, there is no cure for Alzheimer's.

Abstract
Diabetes mellitus is a prevalent cause of mortality worldwide and can lead to several secondary issues, including DWs, which are caused by hyperglycemia, diabetic neuropathy, anemia, and ischemia. Roughly 15% of diabetic patient's experience complications related to DWs, with 25% at risk of lower limb amputations. A conventional management protocol is currently used for treating diabetic foot syndrome, which involves therapy using various substances, such as bFGF, pDGF, VEGF, EGF, IGF-I, TGF-β, skin substitutes, cytokine stimulators, cytokine inhibitors, MMPs inhibitors, gene and stem cell therapies, ECM, and angiogenesis stimulators. The protocol also includes wound cleaning, laser therapy, antibiotics, skin substitutes, HOTC therapy, and removing dead tissue. It has been observed that treatment with numerous plants and their active constituents, including Globularia Arabica, Rhus coriaria L., Neolamarckia cadamba, Olea europaea, Salvia kronenburgii, Moringa oleifera, Syzygium aromaticum, Combretum molle, and Myrtus communis, has been found to promote wound healing, reduce inflammation, stimulate angiogenesis, and cytokines production, increase growth factors production, promote keratinocyte production, and encourage fibroblast proliferation. These therapies may also reduce the need for amputations. However, there is still limited information on how to prevent and manage DWs, and further research is needed to fully understand the role of alternative treatments in managing complications of DWs. The conventional management protocol for treating diabetic foot syndrome can be expensive and may cause adverse side effects. Alternative therapies, such as medicinal plants and green synthesis of nano-formulations, may provide efficient and affordable treatments for DWs.

Abstract
BACKGROUND v-RAF murine sarcoma viral homolog B1 (BRAF) is one of the most frequently mutated kinases in human cancers. BRAF exhibits three classes of mutations: Class I monomeric mutants (BRAFV600), class II BRAF homodimer mutants (non-V600), and class III BRAF heterodimers (non-V600). METHOD In this manuscript, the protein-ligand interaction site of all three mutants: BRAF monomer, BRAF homodimer BRAF2:14-3-32, and BRAF heterodimer BRAF:14-3-32:MEK (Mitogen extracellular Kinase) has been discussed. FDA-approved drugs still have limitations against all three classes of mutants, especially against the second and third classes. Using the DesPot grid model, 1114 new compounds were designed. Using virtual screening, the three PDB Ids 4XV2 for monomers, 7MFF for homodimers, and 4MNE for heterodimers were used for 1114 newly designed compounds. RESULT Dabrafenib, encorafenib, sorafenib and vemurafenib were included as standard drugs. The top 10 hit molecules were identified for each protein. Additional binding studies were performed using molecular docking studies on the protein-ligand site of each PDB identifier. Absorption, distribution, metabolism, excretion (ADME) and toxicity studies were also performed. CONCLUSION It was identified that top-hit molecules had better binding and interaction activity than standard in all three classes of mutants.

Abstract
Chronic inflammation is a common factor in obesity, diabetes mellitus, and the complications of diabetes, including diabetic wounds. These ulcers are characterized by persistent lesions that are challenging to heal, significantly decreasing patients' quality of life and imposing a substantial financial burden on society. MMP are zinc endopeptidases that play a role in wound healing in response to various stimuli, including diabetes mellitus. MMP levels fluctuate throughout the wound healing process in diabetic patients' serum, skin tissues, and wound fluid, indicating their potential as biomarkers for diabetic foot ulcers. Targeting MMP has emerged as a promising strategy for treating diabetic wounds, as these enzymes are involved in critical biological processes related to wound healing, including extracellular matrix secretion, angiogenesis, granulation tissue formation, collagen growth, re-epithelization, inflammatory response, and oxidative stress.

Abstract
Study background < Objective:
Christopher A. Lipinski, in 1997, formulated Lipinski’s rule of five for drug-likeness prediction of potent molecules. It states that molecular weight (less than 500 Daltons), octanol/water partition coefficient (not exceeding more than 5), hydrogen bond acceptor (no more than 10), and hydrogen bond donor (no more than 5) are important for good oral bioavailability. Many drugs among various important classes such as antibiotics, anti-cancer, HIV and HCV protease inhibitors, immunosuppressants, cardiovascular, antifungal, and other miscellaneous classes are approved by FDA or other drug regulatory authorities as clinical use lie beyond the rule of five. In this review, beyond the rule of 5 drugs belonging to these classes (which are either currently approved or under clinical study) are explored and their ADME properties are analyzed.
Material and Methods:
Data of 73 beyond the rule of 5 drugs, belonging to various classes, were collected and their ADME properties were calculated using the Qikprop prediction program of maestro 12.9 module of Schrodinger software.
Result:
Out of 73 drugs, 4 had at least 1 Rule of 5 (Ro5) violation, 16 had at least 2, 31 had at least 3 out of which 22 drugs had 4, Ro5 violations.
Conclusion:
Drugs not obeying the rule of five may also serve as good clinical candidates and potential candidates should not be discarded only on the basis of this rule.

Abstract
Metal complexes in cancer therapy have attracted much interest mainly because metals exhibit unique characteristics, such as redox activity, metal-ligand interaction, structure and bonding, Lewis acid properties etc. In 1965, Barnett Rosenberg serendipitously discovered the metal-based compound cisplatin, an outstanding breakthrough in the history of metal-based anticancer complexes and led to a new area of anticancer drug discovery. Many metal-based compounds have been studied for their potential anticancer properties. Some of these compounds have FDA approval for clinical use, while others are now undergoing clinical trials for cancer therapy and detection. In the present study, we have highlighted the primary mode of action of metallic complexes and all FDA-approved/under clinical trial drugs with reference to cancer treatment. This review also focuses on recent progress on metal-based complexes such as platinum, ruthenium, iron, etc. with potential anticancer activities.

Abstract
Cancer is one of the major healthcare challenges across the globe. Several anticancer drugs are available on the market but they either lack specificity or have poor safety, severe side effects, and suffer from resistance. So, there is a dire need to develop safer and target-specific anticancer drugs. More than 85% of all physiologically active pharmaceuticals are heterocycles or contain at least one heteroatom. Nitrogen heterocycles constituting the most common heterocyclic framework. In this study, we have compiled the FDA approved heterocyclic drugs with nitrogen atoms and their pharmacological properties. Moreover, we have reported nitrogen containing heterocycles, including pyrimidine, quinolone, carbazole, pyridine, imidazole, benzimidazole, triazole, β-lactam, indole, pyrazole, quinazoline, quinoxaline, isatin, pyrrolo-benzodiazepines, and pyrido[2,3-d]pyrimidines, which are used in the treatment of different types of cancer, concurrently covering the biochemical mechanisms of action and cellular targets.

Abstract
The "RAS-RAF-MEK-ERK" pathway is an important signaling pathway in melanoma. BRAFV600E (70-90%) is the most common mutation in this pathway. BRAF inhibitors have four types of conformers: type I (αC-IN/DFG-IN), type II (αC-IN/DFG-OUT), type I1/2 (αC-OUT/DFG-IN), and type I/II (αC-OUT/DFG-OUT). First- and second-generation BRAF inhibitors show resistance to BRAFV600E and are ineffective against malignancies induced by dimer BRAF mutants causing 'paradoxical' activation. In the present study, we performed molecular modeling of pyrimidine-sulfonamide hybrids inhibitors using 3D-QSAR, molecular docking, and molecular dynamics simulations. Previous reports reveal the importance of pyrimidine and sulfonamide moieties in the development of BRAFV600E inhibitors. Analysis of 3D-QSAR models provided novel pyrimidine sulfonamide hybrid BRAFV600E inhibitors. The designed compounds share similarities with several structural moieties present in first- and second-generation BRAF inhibitors. A total library of 88 designed compounds was generated and molecular docking studies were performed with them. Four molecules (T109, T183, T160, and T126) were identified as hits and selected for detailed studies. Molecular dynamics simulations were performed at 900 ns and binding was calculated. Based on molecular docking and simulation studies, it was found that the designed compounds have better interactions with the core active site [the nucleotide (ADP or ATP) binding site, DFG motif, and the phospho-acceptor site (activation segment) of BRAFV600E protein than previous inhibitors. Similar to the FDA-approved BRAFV600E inhibitors the developed compounds have [αC-OUT/DFG-IN] conformation. Compounds T126, T160 and T183 interacted with DIF (Leu505), making them potentially useful against BRAFV600E resistance and malignancies induced by dimer BRAF mutants. The synthesis and biological evaluation of the designed molecules is in progress, which may lead to some potent BRAFV600E selective inhibitors.

Abstract
Diabetes mellitus is a typical life threatening of disease, which generate due to the dysfunction of β cells of pancreas. In 2014, WHO stated that 422 million people were infected with DM. The current pattern of management of diabetes included synthetic or plant based oral hypoglycemic drugs and insulin but drug resentence is become a very big issues in antidiabetic therapy. Thus, it's very earnest to discover now medication for this disease. Now the days, it is well acknowledged that diabetic patients are more prone towards covid and related complications. Thus, medical practitioners reformed the methodology of prescribing medication for covid infected antidiabetic therapy and encouraging the medication contains dual pharmacological properties. It is also well know that polyphenols specifically hold a significant role in oxidative stress and reduced the severity of many inflammatory diseases. Cucumis melo has rich history as ethano-pharmacological use in Indian subcontinent. The fruit and seed is well known for the treatment of various diseases due to the presence of phenolics. Therefore, in this study, the combined mixture of flower and seeds were used for the extraction of polyphenolic rich extract and tested for antidiabetic activity through the antioxidant and in vivo experiments. The antioxidant potential measurement exhibited that the selected plant has the significant competence to down-regulate oxidative stress (DPPH scavenging IC 50 at 60.7 ±1.05 µg/mL, ABTS IC 50 at 62.15 ± 0.50 µg/mL). Furthermore, the major polyphenolic phyto-compounds derived from the Cucumis melo were used for in silico anticovid activity, docking, and complementarity studies. The anticovid activity prognosis reflected that selected phyto-compounds amentoflavone and vanillic acid have optimal possibility to interact with 3C-like protease and through this moderate anticovid activity can be exhibit. The docking experiments established that the selected compounds have propensity to interact with protein tyrosine phosphatase 1B, 11β-Hydroxysteroid dehydrogenase, superoxide dismutase, glutathione peroxidase, and catalase β-glucuronidase receptor. In vivo experiments showed that 500 mg/kg, Cucumis melo ominously amplified body weight, plasma insulin, high-density lipoprotein levels, and biochemical markers. Furthermore, extract significantly downregulate the blood glucose, total cholesterol, triglycerides, low-density lipoprotein, and very low-density lipoprotein.

Abstract
Drosophila, a dipteran insect, has been found to be the best biological model for different kinds of studies. D melanogaster was first described by Meigen in 1830 , is most extensively studied species of the genus Drosophila and a number of investigations employing this species have been documented in areas such as genetics, behaviour, evolution, development, molecular biology, ecology, population biology, etc. Besides D. melanogaster, a number of other species of the genus Drosophila have also been used for different kinds of investigations. Among these, D. ananassae, a cosmopolitan and domestic species endowed with several unusual genetic features, is noteworthy. Described for the first time from Indonesia (Doleschall 1858), this species is commonly distributed in India. Extensive research work on D. ananassae has been done by numerous researchers pertaining to cytology, genetics, mutagenesis, gene mapping, crossing-over in both sexes, population and evolutionary genetics,behaviour genetics, ecological genetics, sexual isolation, fluctuating asymmetry, trade-offs etc. Genome of D. ananassae has also been sequenced. The status of research on D. ananassae at global level is briefly described in this review. Bibliography on this species from different countries worldwide reveals that maximum contribution is from India.

Abstract
INTRODUCTION Infections caused by multidrug resistant bacteria act as a risk factor for mortality in burns patients. So keeping in view the crucial importance of reliable therapeutic decisions of multidrug resistance bacteria and role of hospital environment in bacteria colonization, our study is based on the evaluation of distribution of Pseudomonas sp. and Bacillus sp. in burn patients and burn ward environment. METHODS The present prospective analysis was conducted on the patients undergoing treatment in the Burn ward of Pt. B.D. Sharma University of Health Sciences, Rohtak, Haryana, during the period of January 2012 to March 2013. The multidrug resistant bacteria were characterized by following the CLSI guidelines. Molecular identification isolates were done by amplifying and sequencing 16S rDNA. RESULTS In our study out of 510 samples of 280 burn patients, 263 samples were observed sterile and bacterial isolates were obtained from 247 samples. In burn patients out of 247 samples 43 MDR strains, and in burn ward out of 60 samples 4 MDR strain were observed. After 16S rDNA amplification of MDR isolates the prevalent bacterium was belonged to the genus Bacillus (8 species; 26 isolates) followed by genus Pseudomonas (5 species; 17 isolates). The burn ward environment isolates were Pseudomonas aeruginosa, Pseudomonas stutzeri, Bacillus cereus and Acinetobacter baumanii. CONCLUSION The major finding of our study is the predominance of B. cereus followed by P. aeruginosa in burn patients of Pt. B.D. Sharma University of Health Sciences, Rohtak, Haryana. While considering the role of hospital environment, no direct role of environmental isolates was observed in transfer of bacterial infection.

Abstract
Fluoride concentration of groundwater reserves occurs in many places in the world. A critical area for such contamination in India is alluvial soil of the plain region, consisting of five blocks (Jhajjar, Bahadurgarh, Beri, Matanhail, and Sahalawas) of the Jhajjar District adjacent to the National Capital Territory of India, New Delhi. The purpose of this study was to assess the association between water fluoride levels and prevalence of dental fluorosis among school children of the Jhajjar District of Haryana, India. The fluoride content in underground drinking water sources was found to vary in villages. Hence, the villages were categorized as high-fluoride villages (1.52-4.0 mg F/l) and low/normal-fluoride villages (0.30-1.0 mg F/l). The source of dental fluorosis data was school-going children (7-15 years) showing different stages and types of fluorosis who were permanent resident of these villages. The fraction of dental fluorosis-affected children varied from 30% to 94.85% in the high-fluoride villages and from 8.80% to 28.20% in the low/normal-fluoride villages. The results of the present study revealed that there existed a significant positive correlation between fluoride concentration in drinking water and dental fluorosis in high-fluoride villages (r = 0.508; p < 0.001) and insignificant correlation in low-fluoride villages.

Abstract
The present investigation deals with fluoride removal from aqueous solution by thermally activated neem (Azadirachta indica) leaves carbon (ANC) and thermally activated kikar (Acacia arabica) leaves carbon (AKC) adsorbents. In this study neem leaves carbon and kikar leaves carbon prepared by heating the leaves at 400 degrees C in electric furnace was found to be useful for the removal of fluoride. The adsorbents of 0.3 mm and 1.0 mm sizes of neem and kikar leaves carbon was prepared by standard sieve. Batch experiments done to see the fluoride removal properties from synthetic solution of 5 ppm to study the influence of pH, adsorbent dose and contact time on adsorption efficiency The optimum pH was found to be 6 for both adsorbents. The optimum dose was found to be 0.5g/100 ml forANC (activated neem leaves carbon) and 0.7g/100 ml forAKC (activated kikar leaves carbon). The optimum time was found to be one hour for both the adsorbent. It was also found that adsorbent size of 0.3 mm was more efficient than the 1.0 mm size. The adsorption process obeyed Freundlich adsorption isotherm. The straight line of log (qe-q) vs time at ambient temperature indicated the validity of langergren equation consequently first order nature of the process involved in the present study. Results indicate that besides intraparticle diffusion there maybe other processes controlling the rate which may be operating simultaneously. All optimized conditions were applied for removal of fluoride from four natural water samples.

Abstract
Twelve Indian natural populations of Zaprionus indianus, collected along 22 degrees latitudinal range, were analysed electrophoretically for allozymic variation of esterase gene-enzyme system. Interestingly, all the seven Est loci were found to be highly polymorphic in all the populations of Z. indianus. The genetic structure of Z. indianus populations was characterized by extensive inter-populational genotypic as well as allelic frequency heterogeneity and higher genic differentiation at all the esterase-coding loci. All the polymorphic loci in geographical populations of Z. indianus revealed latitudinal clines, and changes in allelic frequencies were found to correlate with latitude. The occurrence of higher genetic variability in Z. indianus populations was in agreement with its habitat-generalist or broad niche-width characteristics, i.e., the species populations utilized diverse food resources and displayed adaptation to variable climatic conditions. Thus, the observed genic divergence patterns in colonizing populations of Z. indianus could be maintained by balancing natural selection varying spatially along the north-south axis of the Indian sub-continent.

Abstract
A study was conducted in the Jhajjar district of Haryana to assess the fluoride excretion in the population exposed to environmental fluoride and efforts were being made to correlate the results with dental fluorosis. The mean fluoride concentration in drinking water samples of Bahadurgarh, Beri, Jhajjar, Matanhail and Sahalawas blocks of Jhajjar district were 2.05 mg/L, 2.14 mg/L, 2.05 mg/L, 2.14 mg/L and 1.93 mg/L respectively. The mean urinary fluoride concentration was 1.58 mg/L in Bahadurgarh, 1.48 in Beri, 1.50 in Jhajjar, 1.51 in Matanhail and 1.56 in Sahalawas. The mean prevalence of fluorosis on the basis of stage of dental fluorosis was highest of yellowish brown type and on the basis of TSIF score, score 4 type fluorosis was highest in most of the blocks of Jhajjar district. The study revealed that more than 50% of the individuals were found to be affected with flurosis in this district.

Abstract
Twelve natural populations of Z. indianus from India, collected along lines of latitude, were analyzed electrophoretically and the geographical pattern of variation was compared at 15 allozyme loci. Except for Mdh-2, all the loci revealed extensive polymorphism. The allele frequency variation revealed a statistically significant correlation as well as regression coefficients with the latitude. The populations revealed extensive clinical variation at all the polymorphic loci, which depicted moderate to higher FST values. Thus, the observed genetic divergence in colonizing populations of Z. indianus shows the role of natural selection that varies spatially along the north-south axis of the Indian subcontinent.

Abstract
Medical Administrators are usually confronted with the problem of determining the number of doctors to be posted at different health centres within their jurisdiction. In India the number of doctors allocated to a health centre is normally decided without any proper study of the health needs of the area served by the centre. In certain areas the number of doctors posted is considerably different from the requirement of the area. Also, in certain health centres situated in villages lacking in modern amenities, absenteeism among doctors poses a very serious problem in day to day running of the health centres. The problem of allocation is formulated and a heuristic method is suggested for determining the optimum number of doctors to be posted at each health centre in order to maximise the number of patients seen by the doctor per day. The heuristic method is applied to nine health centres of Haryana state of India in order to demonstrate the potential benefits.
