Detection of Human Salivary Amylase Level Deposited on Fruits with First Bite Mark

Background: Human body fluids are vital for criminological examinations. The recovery, conservation, and investigation of body fluids or its stains are critical in measurable forensic cases. The amylase testing is being utilized as a possible test to locate the crime scene saliva stains for more than three decades. This investigation was intended to decide the human salivary amylase accumulated on fruit after the first bite where the level of salivary amylase was concluded by Radial Gel Diffusion method.Methods: Three sorts of organic fruits (apple, peach, and apricot) and 20 people (10 male and 10 female) were chosen for this investigation. The specimens were assembled from bite mark area following time intervals 0 hours, 12 hours, 24 hours, 36 hours and 48 hours.Results: Experimental outcomes demonstrated that the diameter of amylase activity in male specimens was more noteworthy than female. Apples, as well as apricot pit samples, indicated amylase activity till 48 hours; however, the specimens collected from peach demonstrated amylase activity until 12 hours, after first bite mark.Conclusion: This study demonstrated that salivary amylase testing might be valuable for DNA evidence, where DNA investigations for every case might be restricted because of cost issues.Keywords: Amylase; Saliva; Investigation; Bite mark; Preservatio

Glyphosate: cancerous or not? Perspectives from both ends of the debate

Glyphosate is non-selective herbicide. Studies published in the last decade, point towards glyphosate toxicity. Shikimic acid pathway for the biosynthesis of folates and aromatic amino acids is inhibited by glyphosate. Glyphosate carcinogenicity is still considered to be a controversial issue. The World Health Organizations’ International Agency recently concluded that glyphosate is “probably carcinogenic to humans.” Some researchers believed that glyphosate is not linked with carcinogenicity

Mutation pattern in rifampicin resistance determining region of rpoB gene in multidrug-resistant Mycobacterium tuberculosis isolates from Pakistan

The current study was undertaken to characterize the RRDR rpoB gene mutations among the rifampicin-resistant Mycobacterium tuberculosis (MTB) isolates from Pakistan. Rifampicin mutation patterns were analyzed by using PCR followed by rpoB gene sequencing. Among the 1080 referred TB cases, 63 (6%) were resistant against at least one first-line TB drug. Out of these 63 resistant isolates, 24 isolates (38%) were found to be resistant to isoniazid and rifampicin. Sequence analysis of multidrug-resistant tuberculosis (MDR-TB) isolates detected a single mutation in the RRDR region of the rpoB gene at codon 531, 516, 512, 528 and 533; however, 5 MDR-TB isolates lack any mutation in the RRDR region. A double mutation was observed in 1 MDR-TB isolate at codon 512 and 516 which are reported for the first time from Pakistan. Moreover, in 1 isolate a novel silent mutation was observed at codon 528. Further studies about these mutations may be helpful in the development of diagnostic tools for the detection of MTB in a high TB endemic area like Pakistan

Biotransformation of Agricultural By-Products into Biovanillin through Solid-State Fermentation (SSF) and Optimization of Different Parameters Using Response Surface Methodology (RSM)

Vanillin is a flavorful and aromatic secondary metabolite found in vanilla plants. Natural vanillin, produced through processed vanilla beans accounts for scarcely 0.2% of industrial requirements. Vanillin produced via chemical methods and microbial fermentation fills the remaining gap. Among naturally available precursors for biovanillin synthesis, ferulic acid is widely used because of its structural similarity and abundant availability. Herein, various agricultural lignocellulosic by-products (sugarcane bagasse, wheat straw, rice straw, rice bran, and corn cob) were scrutinized for their ferulic acid content, and their biotransformation into biovanillin was examined by solid-state fermentation (SSF). Then, different physicochemical parameters, i.e., moisture content, pH, temperature, inoculum size, and incubation days, were optimized to achieve a high yield of biovanillin using central composite design (CCD) of response surface methodology (RSM). Among agricultural by-products tested, sugarcane bagasse produced 0.029 g/100 g of biovanillin using Enterobacter hormaechei through SSF. After optimization, the highest concentration of biovanillin (0.476 g/100 g) was achieved at a moisture content of 70%, temperature of 37.5 °C, pH 7.5, inoculum size of 4 mL and incubation time of 48 h. The F-value of 6.10 and p-value of 0.002 evidenced the ultimate significance of the model. The significance of the constructed model was supported by the 91.73% coefficient of determination (R2), indicating that the effects of moisture, pH, and temperature were significant. HPLC and FTIR confirmed the sample identification and purity (was reported to be 98.3% pure). In conclusion, sugarcane bagasse appears to be a cost-effective substrate choice for large-scale biovanillin production

Genotypic and Phenotypic Characterization of Erythromycin-Resistant <i>Staphylococcus aureus</i> Isolated from Bovine Mastitis and Humans in Close Contact

Staphylococcus aureus (S. aureus) is a major causative agent of mastitis and is resistant to many antibiotics. Thus, there is a need to characterize the genetic determinants of S. aureus erythromycin resistance, such as ermA, ermB and ermC. The current study aimed to determine the phenotypic and genotypic erythromycin resistance profile and relatedness of S. aureus recovered from bovine mastitis and humans in close contact. A total of 14 mastitis-infected buffalo milk samples and 16 samples from their respective milkers were collected from different farms of Lahore, Pakistan. The antibiotic resistance profile was determined through the disk diffusion test. The overall prevalence of S. aureus in mastitis-affected buffaloes was found to be 75%, of which 52.1% were resistant to erythromycin and 42.8% to clindamycin. S. aureus isolates recovered from milker nasal samples showed 56.25% resistance to erythromycin and 44% resistance to clindamycin. Genotypic antibiotic resistance profiles were determined from 14 milk samples through PCR. Overall, eight (52.1%), three (21.4%) and five (35.7%) S. aureus isolates were positive for the ermA, ermB and ermC genes, respectively. Moreover, 16 milker nasal S. aureus isolates were also tested for the presence of ermA, ermB and ermC genes. The ermA, ermB and ermC genes were observed in nine(56.7%), five (31.3%) and seven (43.7%) isolates, respectively. A significant association was shown between phenotypic and genotypic erythromycin resistance. The results indicate both that there are sufficient genetic similarities, and the actual transmission of erythromycin resistance genes between these two hosts of S. aureus.</i
