The continuous practice of traditional medicines provides scientific validation of the use of herbal medicines, which eventually leads to widespread recognition among the socioeconomic healthcare systems. Anaphalis triplinervis, (Asteraceae) is native species being used to prevent, treat, and cure the hepatic ailment, in Chinese and Indian traditional systems of medicine. we investigated the hepatoprotective effect of A. triplinervis extracted with hydroethanolic solvent (HEEAT) a potent natural anti-oxidant against carbon tetrachloride-induced hepatic injury in rats and elucidate the inflammatory cascade leading to apoptosis in adult rat liver. Adult Wistar rats were randomized into 6 groups and each group contains six animals, (n=6). Group I: normal control; animals treated with vehicle. Group II: toxin control; rats administered with CCl4+Olive oil 1:1 i.p., Group III: standard; silymarin (125 mg/kg), Group IV, V, and VI administered with HEEAT 100, 200, 300 mg/kg up to 14 days. The body weight and hematological assessment were performed further the antioxidant activity was determined by assay for catalase, glutathione reductase, superoxide dismutase, and malondialdehyde in the hepatic tissue. Increased oxidative stress, cytokines (TNF-alpha and IL-1beta), NF-kappa β, and caspase-3 levels in CCl4-treated rats. Co-administration with HEEAT significantly prevented all the biochemical and molecular alterations in the hepatic tissue of CCl4-treated rats in a dose-dependent manner. The hepatoprotective effect was further confirmed by examining the liver organ weight and histopathological analysis using H&E staining. Collectively the findings from the current study demonstrate the possible involvement of oxidative- stress-mediated activation of inflammatory cascade and apoptosis in chronic CCl4-induced liver injury and suggest the effectiveness of HEEAT in mitigating the liver toxicity associated with chronic CCl4 administration. Further, our study using morphological, hematological, biochemical, histopathological data analysis suggest that HEEAT may serve as an effective antioxidant and hepatoprotective candidate.

According to an international conference on harmonization (ICH), elemental impurities can come into drug products from various sources. These elemental impurities thus have to be quantified in drugs. Atorvastatin calcium is a widely used drug to treat cardiovascular diseases. Nickel used as a catalyst during the synthesis process of atorvastatin calcium can cause toxicity to humans and, hence, have to be quantified. A simple, efficient, and accurate, validated method was developed to estimate nickel content as an elemental impurity in atorvastatin calcium using atomic absorption spectroscopy (AAS) with 0.2 nm slit width with a nickel hollow cathode lamp. Acetylene and air mixture was used for flame with 232.0 nm wavelength. The system performance was evaluated by performing the system suitability parameters. The limit of detection and limit of quantification were found to be 0.086 mg/mL and 0.23 mg/mL, respectively. Accuracy studies recoveries were performed at three spiking levels at 50%, 100%, and 150%, and the results were found to be 92.67%, 91.33%, and 91.00%, respectively. It concludes that according to the United States Pharmacopeia (USP) <232>, this developed and validated atomic absorption spectroscopy method for determining nickel in atorvastatin calcium medication substance was within the permitted limit.

The rs1799983 T>G genotyping showed three types of genotypes; GT, GG and TT. Non-significant differences were observed for all genotypes. The GG frequent percent was 50% in SLE and 56% in control group (p 0.641), GT was more frequent in SLE than control (47.36% and 40%), respectively (p 0.688), and low percent’s of TT in both group (2.63% and 4%). Low T allele percentage in SLE and control, high frequent of G allele in both groups. According to malar rash, a high percent of GT frequency in the patients with malar rash (71.42%) than non malar rash group (41.93%) there was non-significant association of all genotypes with malar rash (p 0.223 and p 0.906) for GG, GT and TT, respectively. The allele frequency shows significant association (p 0.000), G was more frequent in malar rash than non-malar rash group (0.64), while T low percentage in malar rash than another group (0.35). belong to sex, significant association was observed in GG with female and GT with male (p 0.0002), the TT non-significant association with sex, the allele frequency showed non-significant association with sex despite of the high percent of G allele in both male and female, The genotyping frequency distribution according to SLE treatment, in the Rituximab the GG and GT was more frequent, then in the endoxan that the GG and GT have a same frequent, the methylperdnislon was little used as treatment and has same frequent of GG and GT. The current study concluded that no association between eNOS rs1799983 T>G and SLE, malar rash and weak association with SLE treatment, but significant association was observed in GG with female.

Bacteroides species are the most common gram-negative anaerobic bacteria identified in surgical site infections as per our studies. Diabetic foot and burn wound infections have higher chances of surgeries and use of metronidazole for the treatment of anaerobic infections may lead to metronidazole resistance. There is a requirement for up-to-date geographical and therapeutically relevant data for Bacteroides species. The purpose of this study was to identify the rate of Bacteroides species with metronidazole resistance. We had collected 100 samples from burn wounds and diabetic foot ulcers in Robertson Cooked Meat (RCM) broth. Then it was sub-cultured on anaerobic blood agar in a gas pak jar. Isolates were identified based on culture morphology and standard biochemical techniques. Antimicrobial sensitivity was evaluated by using several frequently used antimicrobial agents as per CLSI. A total of 52 anaerobic bacteria were isolated. In gram negative Bacteroides species, there were 34.61%, while in gram positive Peptostreptococcus species, there were 42.30%. 11.11% (4/18) of Bacteroides species were resistant by to metronidazole and had the same 11.11% (4/18) were resistant to piperacillin-tazobactum. In Pepetostreptococcus resistance to penicillin was about 72% (16/22) and 18% (2/22) in Metronidazole. Eubacterium species were 50% resistant to piperacillin-tazobactum and clindamycin. Fusobactrium species were totally resistant to penicillin.

One of the most dangerous pollutants in water are pharmaceutical, which were treated with the use of easy, simple and inexpensive. The adsorption process depends on the use of available and inexpensive surfaces. In this study, it relied on the use of clay (Bentonite), where several factors were studied, including the effect of surface weight, the effect of drug concentration and function. The acidity isotherms were also studied, and it was based on measuring the concentration of the residual from the adsorption process with the formation of the colored complex. In this paper, a fast, inexpensive, simple and highly sensitive colorimetric method was used for the determination of the amino drug (4-Aminoantipyrine 4AAP). A new azo dye was prepared by the diazanium process in the presence of acidic medium and the formation of diazanium salt, which reacts with a reagent in the presence of an alkaline medium to form azo dye with violet color. Several factors have been studied to develop the color of the compound and to obtain the best absorption and high sensitivity. Among these factors are the effect of reagent volume, effect of base volume and quality, effect of temperature, effect of addition order and type of reagent. This colorimetric method is very suitable for the determination of 4AAP in commercial pharmaceutical formulations such as.tablets and capsules to give a stable color for three hours. This method is characterized by its color accuracy and high accuracy, as well as high sensitivity for drug estimation.

Normal aerobic cellular metabolism, therefore, generates free radicals. An instinctive antioxidant device of the frame performs an influential function inside any damage due to free radicals’ prevention by the body’s antioxidant mechanism. Conversely, an imbalanced process of antioxidants, overconsumption, or assimilation of loose militants as of the environment to the dwelling device ensuing in neurodegenerative sicknesses, reasons neural cells to travel through purposeful or sensory loss. Moreover, numerous different environmental or genetic factors, oxidative stress (OS) are the primary motives for the atom assault on neural cells that contribute a ruinous function to neurodegeneration. Although oxygen is additionally a should, imbalanced antioxidants and extra reactive oxygen species (ROS) outcomes in quite a few continual problems like cancer, diabetes, coronary heart sicknesses, and neurodegenerative sicknesses similar to Alzheimer’s disease (AD), Parkinson’s disease (PD), aging, also plenty more and lots of varied neural problems. Recently, Several Antioxidants are being hired upon as resounding healing towards dementia that reversing age-associated declines in neurocognitive performances and excessive neuronal loss, as they will prevent oxidative pressure via way of means of neutralizing loose radicals. Diet is a chief supply of antioxidants and plant natural flavonoids, are catching interest to be an advert supply of phytonutrients at this time. Here, we review how C. elegans has been utilized for understood oxidative stress and neurodegenerative diseases therapeutic. Specifically, we will discuss the mechanisms that lead to free radicals that disrupted the antioxidant system and the pharmacological therapy that has been in use for a long time, and novel therapies in an oxidative stress consequence.

Nickel is a suspected immunotoxic and immunomodulatory agent and an allergen in humans in its elemental form. Also, nickel is a carcinogen that can cause multiple types of cancer in humans. According to the international council for harmonization (ICH) quality guideline ICH Q3D (R1), nickel falls under category 2A. It means that nickel has a high chance of occurring in drugs, and hence the risk assessment must be done compulsorily. The goal of this review is to summarize how various analytical methods such as X-ray photoelectron spectroscopy, atomic absorption spectroscopy, and inductively coupled plasma spectroscopy have been used to quantify nickel as an elemental impurity in various sample materials such as pharmaceutical drugs, cosmetics, blood plasma, and environmental water and soil samples, among others. This evaluation serves as a guide to determining the optimal analytical approach for estimating nickel based on several aspects such as sample type, sensitivity required, skill, and method cost.

Background: Osteoporosis is a condition that can have a significant influence on many postmenopausal women’s lives. As the population ages, osteoporosis with its potentially fatal consequence of fracture is becoming more common and assessing bone health is an important part of a woman’s normal care. More tangible efforts are required for osteoporosis patient prevention, early diagnosis, and practicable and inexpensive management. We anticipated that biochemical markers could allow for dynamic and quick measurements of total body skeletal metabolism, which could be useful in the treatment of postmenopausal osteoporosis (PMO) as well as evaluating the effectiveness of antiresorptive therapy. Aim: Biochemical Studies in Osteoporosis of Women in Central India. Material and Method: The present study was conducted at the Department of Biochemistry, Datta Meghe Medical College and Shalinitai Meghe Hospital Nagpur and JNMC Sawangi Wardha. The postmenopausal women in the age group of 45 to 60 years and diagnosed as osteoporosis by clinician were selected as study group. Results: This study demonstrates that osteoblastic activity as assessed by bone formation marker is elevated in PMO. Osteocalcin is a promising marker of bone turnover & it can provide dynamic status of bone remodeling. Simple, straightforward, low-cost biochemical markers such as blood calcium, ALP, albumin, and phosphorus could be employed as indicators of accelerated bone turnover in routine biochemical studies in osteoporosis of 150 women to enable early management to reduce fracture owing to osteoporotic changes. The combined use of bone mineral density (BMD) and these biochemical markers will be of great help to the treatment decisions and to monitor effect of therapy. Conclusion: Acute variations in bone turnover rate are reflected by biochemical indicators of bone. Bone turnover lowers in PMO women on antiresorptive medication, as evidenced by lower levels of marker. Changes in the concentration of these indicators can be used to track how effectively a treatment is working. Antiresorptive therapy-induced decreases in marker levels may be an early indicator of eventual BMD increases and a reduction in fracture risk.
