The purpose of the study was to systematically review and assess the safety and efficacy of hemostatic agents in tubeless percutaneous nephrolithotomy. Original studies on the use of hemostatic agents in tubeless percutaneous nephrolithotomy (PCNL) from January 2001 to March 2014 were searched in Ovid, Science Direct, Pubmed, and Embase by two independent reviewers. A drop in hemoglobin (Hb), analgesic requirements, length of hospital stay, and necessity for blood transfusions were compared using Review Manager 5.2. The methods were done according to the Cochrane Handbook for interventional systematic reviews and written based on the PRISMA Statement. Seven studies involving 351 patients met the inclusion criteria for the meta-analysis. The baseline characteristics were comparable in all of the studies. The results showed that the length of hospital stay was less in the experimental group than in the control group (P < 0.05). There were no significant statistical differences in terms of a drop in Hb, analgesic requirements, and the necessity for a blood transfusion between the two groups (P > 0.05). The meta-analysis indicated that the hemostatic agents in tubeless PCNL were not expected to be unsafe or mandatory, but that they were expected to be expensive. We concluded that hemostatic agents might not be necessary in tubeless PCNL.

Background/objectives: Amyloid peptides, whose accumulation in the brain as senile plaques is associated with the onset of Alzheimer's disease, are also found in cerebral vessels and in circulation. In the bloodstream, amyloid peptides promote platelet adhesion, activation, oxidative stress, and thrombosis, contributing to the cardiovascular complications observed in Alzheimer's disease patients. Natural compounds, such as curcumin, are known to modulate platelet activation induced by the hemostatic stimuli thrombin and convulxin.

Aging is an inevitable aspect of life, but age-related diseases are not an inseparable part of the aging process, and their risk can be reduced through a healthy lifestyle. Vitamin K has a broader impact than just blood clotting, and yet it remains overshadowed by other vitamins and underestimated by both doctors and consumers. Vitamin K (VK) is a multifunctional micronutrient with anti-inflammatory and antioxidant properties, whose deficiency may cause age-related diseases such as cardiovascular diseases, neurodegenerative diseases and osteoporosis.

Antimicrobial compounds of natural origin are of interest because of the large number of reports regarding the harmfulness of food preservatives. These natural products can be derived from plants, animal sources, microorganisms, algae, or mushrooms. The aim of this review is to consider known antimicrobials of natural origin and the mechanisms of their action, antimicrobial photodynamic technology, and ultrasound for disinfection.

mRNA-based vaccines against the COVID-19 pandemic have propelled the use of nucleic acids for drug delivery. Conventional lipid-based carriers, such as liposomes and nanolipogels, effectively encapsulate and deliver RNA but are hindered by issues such as premature burst release and immunogenicity. To address these challenges, cell membrane-coated nanoparticles offer a promising alternative.

In this article, we report on the research on the synthesis of composites based on a porous, highly ordered silica material modified by a metallic nanophase and chitosan biofilm. Due to the ordered pore system of the SBA-15 silica, this material proved to be a good carrier for both the biologically active nanophase (highly dispersed silver nanoparticles, AgNPs) and the adsorption active phase (chitosan). The antimicrobial susceptibility was determined against Gram-positive ATCC 25923, Gram-negative bacterial strains ( ATCC 25922, ATCC 700603, and ATCC 27853), and yeast ATCC 90028.
