Gelatin is used as an ingredient in both food and non-food industries as a gelling agent, stabilizer, thickener, emulsifier, and film former. Porcine skins, bovine hides, and cattle bones are the most common sources of gelatin. However, mammalian gelatins are rejected by some consumers due to social, cultural, religious, or health-related concerns. In the present study, gelatin was obtained from camel skin as an alternative source using a combination of processing steps. Central composite design combined with response surface methodology was used to achieve high gelatin yields under different extraction conditions temperatures of 40, 60, and 80 °C; pH values of 1, 4, and 7; and extraction times of 0.5, 2.0, and 3.5 min. Maximum gelatin yield from camel skin (29.1%) was achieved at 71.87 °C and pH 5.26 after 2.58 min. The extracted gelatin samples were characterized for amino acid profile, foaming capacity, film formation, foam stability, and gel strength (Bloom value). Gelatin nanoparticles were produced, and their morphology and zeta potential were determined. Bloom value of the camel skin gelatin was 340 g. Amino acid analysis revealed that the extracted gelatin showed high glycine and proline contents. Analysis of camel skin gelatin nanoparticle and functional properties revealed high suitability for food and non-food applications, with potential use in the growing global halal food market.Human papillomavirus (HPV) is a causative agent of cervical and other cancers. Sexually transmitted Infections (STIs) may play a crucial role in HPV persistence, leading to serious complications, including cervical cancer. This study investigated the association of HPV/STI co-infection in cervical samples with cervical dysplasia among women in Saudi Arabia. HPV-positive cervical samples (n = 142) were obtained from previous studies and newly collected samples (n = 209) were obtained from women aged 19-83 years. For HPV detection and genotyping, PCR and Genoflow HPV assay kits were used. STIs were detected using a Genoflow STD array kit. Of 351 samples, 94 (27%) were positive for STIs. Among HPV-positive samples, 36 (25%) were positive for STIs; the most common pathogens were Ureaplasma urealyticum/Ureaplasma parvu (13%) and Mycoplasma hominis (6%). A global significant correlation was detected between HPV and STIs with progression of abnormal cervical cytology (χ2 = 176, P less then 0.0001). Associations between cervical cytology diagnosis and HPV status, STI types (opportunistic and pathogenic), and the presence of Ureaplasma spp., and Mycoplasma hominis were significant (P less then 0.05). Our results suggest that additional study in a larger population is warranted to determine the association between HPV/STI co-infection and cervical neoplasia in Saudi women.The burden from microbial diseases has to be addressed in an increasing pace due to multidrug resistance, causing clinical annoyance, globally. Indeed, employing eco-friendly approaches by green syntheses of nanoparticles with metals/metalloids as antibacterial compounds would be continual and cost-effective. Herein, the synthesis of silver nanoparticles (AgNPs) by aqueous extracts of the cyanobacterium Chroococcus minutus (strain, CRLSUM10), collected from the meeting point of sea and river, East coast of India, are presented; both reducing and stabilizing mediators of the synthesized AgNPs were ascertained, by characteriztion by UV-visible spectrophotometry, XRD, FTIR, SEM and SEM-EDX. Furthermore, synthesized AgNPs had a remarkable antibacterial activity at the lowest dose, 100 mg against pathogenic strains of E. coli and S. pyogenes, rendering those as novel antibacterial agents against 'upper respiratory tract infection'.Supplementation of the growing substrate by nitrogenous additives has been known to improve the production of oyster mushroom (Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm. (1871)). However, the application of nano-additives has not been reported in such cultivation yet. The study investigated the effect of nano-urea added in two different doses (3 g and 5 g per kg substrate), once (at spawning or after first flush) or twice (at spawning and after first flush) to the growing substrate consisting of wheat straw and spent oyster substrate (11, w/w). Results showed that the application of nano-urea once has induced the highest number of mushroom flushes (four flushes) despite the dose applied. Contrarily to early findings, where high doses of nitrogen have caused inhibition of mushroom growth and production, nano-urea application has had better effects when applied twice. With 5 g/kg, it induced the shortest period between the first and the third flush (15 days). With 3 g/kg, it resulted in the highest biological and economic yields at the third flush (332.7 g/bag and 283.1 g/bag respectively), in total (973.4 g/bag and 854.0 g/bag respectively), the highest biological efficiency (109.6%), and pileus diameter/stipe length ratio (2.8). Experimental findings of the current study may be potentially applied at commercial scale.Objective To investigate the effect of latanoprost on intraocular pressure (IOP), visual acuity and C-reactive protein (CRP) in patients with primary open-angle glaucoma (POAG). Methods A total of 163 POAG patients (266 eyes) admitted to our hospital from February 2015 to July 2017 were selected and divided into observation group (81 cases, 132 eyes, latanoprost eye drops) and control group (82 cases, 134 eyes, timolol maleate eye drops) according to different treatment plans. The clinical efficacy of the two groups after treatment was evaluated. The IOP, visual acuity and CRP level were compared between the two groups before and after treatment. learn more Then the adverse reactions of the two groups were observed and recorded. Results After treatment, the total effective rate was 92.59% (75 cases) in the observation group and was 80.49% (66 cases) in the control group, with statistic difference between groups (P 0.05). Conclusion Latanoprost can improve IOP, visual acuity, and CRP levels. It improves eye hemodynamics, and has significant efficacy in treating primary open-angle glaucoma. Also, it has good security.
