A new nutrient medium for isolation and cultivation of the causative agents of enteric yersiniosis and pseudotuberculosis was found to have advantages over Endo medium in its differentiating and inhibiting properties. This medium permitted the easy differentiation of Yersinia pseudotuberculosis from Y. enterocolitica, as well as from Escherichia coli, Shigella flexneri, Klebsiella pneumoniae, K. rhinoscleromatis, Hafnia, Enterobacter and Citrobacter by color; from Proteus inconstans by swarming. In addition, weakly swarming of P. vulgaris differed by their light bluish color and Pseudomonas aeruginosa, by the brilliance and size of colonies. Endo medium could be used only for differentiation of E. coli from lactose-negative Yersinia colonies, Klebsiella (by mucous growth) and, to a certain extent, all Proteus species (by swarming). The medium under test and the control medium inhibited the growth of Staphylococcus aureus. In contrast to Endo medium, the medium under test partially inhibited the growth of K. rhinoscleromatis and the swarming of P. inconstans. The new medium is now introduced into practice.

Introduction: Breast cancer resistance protein (BCRP) is an efflux membrane transporter that controls the pharmacokinetics of a large number of drugs. Its activity may change when taking some endo- and exogenous substances, thus making it a link in drug interactions.
Aim: The aim of the study was to develop a methodology for testing drugs for belonging to BCRP substrates and inhibitors in vitro.
Usefulness of Mesh Reinforcement in Pubic Fixation Urethral Sling Surgery for Urinary Incontinence After Radical Prostatectomy.

Objectives: In our institution, a unique sling technique is performed for urinary incontinence after radical prostatectomy. However, in cases of severe urinary incontinence or in the medium to long term, the therapeutic effect may be insufficient. Therefore, a urethral sling technique that provides stronger compression of the bulbar urethra was developed, and its effectiveness was compared with the conventional technique.

Compared with the energetically favorable 5- or 6-membered fluoro-functionalized heterocycles, the construction of medium-sized fluoro-heterocycles is relatively under-researched because of their inherently unfavorable enthalpic and entropic nature. Based on rational design and DFT calculations, a novel photocatalytic difluoromethyl radical-initiated intramolecular 7--trig cyclization was realized, thus affording a sustainable route for the synthesis of challenging fluoro-functionalized medium-sized -heterocycles. Depending on atomic dipole moment corrected Hirshfeld population (ADCH) charge calculations, the chemoselective 6--trig radical cyclizations were further replenished.

IS ESG EFFECTIVE IN THE TREATMENT OF OBESITY AND ASSOCIATEDCOMORBIDITIES?: Endoscopic Sleeve Gastroplasty (ESG) is more effective than lifestyle modifications alone for weight loss and improving obesity-related comorbidities. While it has less effect on weight loss compared to Laparoscopic Sleeve Gastrectomy (LSG) in the short to medium term, it offers similar comorbidities resolution to LSG. IS ESG A SAFE PROCEDURE, AND WHAT ARE ITS RISKS?: The safety profile of ESG is consistently supported in the literature.

The bovine conceptus elongates near Day 16 of development and releases interferon-tau (IFNT), disrupting the endometrial luteolytic mechanism to sustain luteal P4 and pregnancy. Conceptus factors other than IFNT modify local endometrial activities to support pregnancy; however, the microenvironment is largely uncharacterized. We utilized a bovine conceptus-endometrial culture system to elucidate the microenvironment in the form of RNA and protein.
