In this study, the efficacy and safety of DKB-131 (extract of Siraitiagrosvenorii) in adults of both genders presenting mild symptoms of knee arthritis were evaluated in comparison to a placebo. This clinical trial was randomized, double-blind, multicenter, and lasted for 12 weeks. A total of 120 participants with Visual Analogue Scale (VAS) scores of 30 mm or higher in the knee area and Kellgren & Lawrence Grade I or II knee arthritis on X-ray were enrolled, with 60 subjects randomized to receive DKB-131 and 60 subjects receiving placebo. Following 12 weeks of consumption, the change in K-WOMAC total score assessed in the per protocol (PP) set revealed a reduction of 21.86±15.98 points in participants who received DKB-131 (p<0.0001), whereas those in the placebo group exhibited a reduction of 14.92±16.66 points (p<0.0001). This demonstrated a statistically significant difference between the test groups (p=0.0389). Additionally, significant differences were observed between the DKB-131 and placebo groups in the changes in K-WOMAC pain (p=0.0157) and physical function (p=0.0447). For the secondary efficacy endpoint, the change in Visual Analogue Scale (VAS) scores, analyzed in the PP set after 12 weeks of consumption, the test group showed a reduction of 17.82±13.80 mm (p<0.0001), while the control group exhibited a reduction of 11.81±13.99 mm (p<0.0001), indicating a statistically significant difference between the test groups (p=0.0359). Safety evaluations including hematological tests, biochemical tests, and urinalysis revealed no clinically significant differences between the consumption groups. Additionally, vital signs (pulse, blood pressure) and anthropometric measurements (body weight) did not exhibit clinically significant differences between the consumption groups, confirming the safety of DKB-131. We propose that the consumption of DKB-131 is safe for humans and may contribute to joint health. Trial registration (CRIS.NIH.go.Kr): KCT0008527

In Pakistan, production of poultry has been evolved as a good alternate of beef and mutton. In this study multiplex PCR approaches were adopted to differentiate and detect avian mycoplasma in a single PCR reaction as a step forward in the economization of PCR detection. From the total of 25 samples, 25 (100%) had a positive Mycoplasma isolation result. The biochemical test yielded the highest number of isolations, with MG accounting for 10/25. Commercial DNA-based PCR kits have been developed as a result of recent advancements in diagnostic techniques for Mycoplasma infections. Tetracyclines, fluoroquinolones, tilmicosin, tylosin, spiramycin Infections should be reduced as much as possible.

Laccase enzyme production is important and more beneficial for environment, because it has many roles like, involved in bioremediation, biodegradation, decolorization of environmental polluted dyes and pharmaceutical sector also. Production of laacse enzyme from bacillus sp as using of Agro waste (rice bran) as a substrate. The Agricultural soil sample was collected, after the sample were processed for the preliminary and biochemical tests to identification of Bacillus organism. The Guiacol inducer were used for microbial screening of laccase enzyme production. After that microbial screening, various optimization parameters (pH, Temperature, Inducers, carbon and nitrogen sources) are checked for that production of laccase enzyme in mass level. Based on that optimization the bulk fermentation (large scale) (solid state fermentation) were done as a rice bran substrate. The fermentation product was subjected to analyzed the physiochemical properties and purification based on that techniques of Gel filtration chromatography, Dialysis, Ammonium sulfate preciptation. The protein estimation of that product to analysed by lowry’s method.

Microorganisms are the main cause of food-borne illness in humans that may occur by consuming unhygienic products from poultry and other sources. With the passage of time bacterial resistance to antibiotics is ever-increasing which necessitates development of new antibiotics. One of the most obvious reasons of antimicrobial resistance in human-beings is the consumption of contaminated food with microbes. The aim of present study is to isolate, identify and characterize the food-borne pathogens from chicken eggs. For this purpose, a total of 240 egg samples were collected from eight different towns of Faisalabad. Samples were collected from egg surface, yolk, albumin and egg tray. Isolation, identification and characterization of commonly occurring egg borne pathogens including E. coli, Salmonella spp., Bacillus subtilis, Staphylococcus aureus were carried out by different cultural, morphological and biochemical tests. Antibiotic resistance pattern of recovered bacterial pathogens was determined by disk diffusion method (Kirby-Bauer). Zone of inhibition was measured through vernier calliper. The results revealed a high prevalence of Salmonella entitidis with 40.83% following Staphylococcus aureus with 22.08%, Escherichia coli with 17.92% and Bacillus subtilis in a lower ratio with 2.5%. The antibiotic sensitivity test showed different resistance patterns of the isolated microbes. For this purpose, five different drugs were used that included cefotaxime, tetracycline, gentamicin, levofloxacin and penicillin. Bacillus subtilis was highly resistant to penicillin and cefotaxime. Whereas, E. coli showed resistance to three antibiotics that were tetracycline, cefotaxime and penicillin. The only drug to which Staphylococcus aureus showed resistance was cefotaxime. Salmonella was resistant to tetracycline and gentamicin. The study concluded that chicken egg is contaminated with a number of bacteria that could be pathogenic or not. So, there is need of proper attention to cope up with possible future egg-borne illnesses.

The concern over exposure to drinking water contaminated and the resultant adverse effect on human health has prompted several studies evaluating the quality of drinking water sources. This study was carried out to determine the bacteriological and Physico-chemical qualities of commercial borehole water within Otuoke community in Bayelsa state Nigeria. Ten (10) water samples were collected from the various locations designated as (A-J). The Physico-chemical parameters were determined by using the photometric technique through the Colour Q photometer and the bacteriological analysis was determined by using aerobic plate method. The Physico-chemical parameters of the water samples analysed were within the acceptable limit of WHO standard of drinking water quality except for Bromine and cyanuric acid which ranged from 1.6±0.1 to 2.7±0.1 and 2±1 to 9±1 respectively. The Result of total bacteria count obtained from the borehole water samples ranged from 1.1 x 105cfu/ml to 6.9 x 105cfu/ml and there was no detected growth for the faecal coliform count of most of the samples except for BHW-I and BHW-J which had 1.3 x 104 to 7.9 x 104 respectively. Bacteria isolated and identified using conventional biochemical test include E. coli (17.9%), Klebsiella spp. (35.7%), Salmonella spp(25.0%), Enterobacter aerogenes (21.4%) The study therefore suggests that all the borehole water tested in Otuoke and environs are considered unsafe for consumption and therefore regular treatment before usage is recommended.
