Phylogeographic investigation of tick-borne pathogens in host-seeking Dermacentor marginatus in Anatolia: Significant correlation between population genetic structure and SFG rickettsiae.

Characterizing the population structure of vector ticks and their associated microorganisms in natural foci is essential for understanding of the ecology of tick-borne disease (TBD) and developing effective control strategies. Dermacentor marginatus is an important vector species in the Palearctic realm, yet its vectorial role remains poorly defined, particularly due to the lack of studies integrating population genetics with pathogen data. In this study, we performed a phylogeographic analysis of tick-borne pathogens (TBPs) in host-seeking D.

Exploring the complex interplay of Blastocystis, morbid obesity, and bariatric surgery on gut microbial dynamics.

This study examines Blastocystis dynamics in 15 individuals undergoing sleeve gastrectomy. Molecular detection involved DNA extraction, RT-PCR, and sequencing, while 16S rRNA sequencing via Illumina MiSeq analyzed the intestinal microbiome. Statistical analysis through SPSS considered a significance level of p < 0.

Preconcentration of bismuth using nickel hydroxide nanoflower from water samples and determination by FAAS.

In this study, a preconcentration strategy based on Ni(OH) nanoflowers (NFs) was developed for the extraction/separation of bismuth ions from environmental water samples before the determination by flame atomic absorption spectrometry (FAAS). The homogeneous coprecipitation method was employed for the synthesis of the flower-shaped Ni(OH) and used as an adsorbent for the preconcentration of bismuth. The extraction variables were determined by a univariate optimization strategy to obtain maximum extraction performance.

SIRT2 deacetylates and decreases the expression of FOXM1 in colon cancer.

New FOXM1-specific inhibitors with the potential to be used for therapeutic purposes are under extensive research. We hypothesized that deacetylation of FOXM1 would decrease protein expression, thus providing novel therapeutic management of colon cancers. Immunostaining was used to determine FOXM1 and SIRT2 expressions in human colon cancer tissue microarrays (n = 90) from Stage I to Stage IV.

Ionic Liquid-Solidified Floating Organic Drop Microextraction for the Preconcentration of Lead in Environmental Water Samples Prior to Its Determination with Electrothermal Atomic Absorption Spectrometry.

This research investigates the utilization of an ionic liquid combination of solidified floating organic drop micro-extraction (IL-SFODME) to augment the concentration of trace amounts of lead, working as a preliminary stage before electrothermal atomic absorption spectrometry (ETAAS) analysis without the use of chelating agents. Key parameters impacting the microextraction efficiency-including pH, the volume of the ionic liquid (1-Hexyl-3-methylimidazolium hexafluorophosphate, HMIMPF6), temperature, extraction time, and stirring speed-were methodically examined to determine optimal conditions. Under detected optimized conditions, an enhancement factor of 71.

Blocking SIG1R Along with Low Cadmium Exposure Display Anti-cancer Qualities in Both MCF7 and MDA-MB-231 Cells.

Sigma-1 receptor (SIG1R) is a chaperone that modulates inositol 1,4,5-trisphosphate receptor type1 (IPR1) calcium (Ca) channels on the endoplasmic reticulum. Therefore, SIG1R functions as an indirect regulator of Ca and acts as an apoptosis modulator. Increased expression of SIG1R is associated with poor prognosis in breast cancers (BC), and SIG1R antagonists like BD1047 induce apoptosis.

Long-term impact of sleeve gastrectomy on serum uric acid levels.

Background: Obesity is a risk factor for hyperuricemia. Bariatric surgery is an effective treatment method for metabolic control. The aim of our study was to evaluate the correlation between the preoperative and postoperative serum uric acid levels with body mass index, body weight, and excess weight loss in patients that underwent sleeve gastrectomy.

Potential associations between alterations in gut microbiome and obesity-related traits after the bariatric surgery.

Background: This study aimed to examine the effects of both obesity and bariatric surgery on gut microbiome, dietary intake, as well as metabolic and inflammatory parameters.

Methods: All participants (15 with morbid obesity who had bariatric surgery, 8 with morbid obesity and 11 non-obese) were followed up for a 6-month period with interviews at baseline (M0), at the end of 3 (M3) and 6 months (M6). Dietary assessment was done, and blood and faecal samples were collected.

Effects of different intraabdominal pressures on internal jugular vein, liver and kidney functions in obese patients undergoing laparoscopic sleeve gastrectomy.

Objective: The aim of this study was to investigate whether there was a difference in laparoscopic sleeve gastrectomy (LSG) performed with either 10 mmHg or 13 mmHg intraabdominal pressures. Effects of these pressures on the internal jugular vein (IJV) diameter and flow along with the liver and kidney function tests were evaluated.

Materials And Methods: The patients were divided into two groups with respect to the intraabdominal pressure performed during LSG (either 10 or 13 mmHg).

Analysis of the Effect of Weight Loss on Eustachian Tube Function by Transnasal Videoendoscopy.

Objective: To investigate the effect of weight loss after bariatric surgery on eustachian tube (ET) function with video endoscopy.

Materials And Methods: The present study was conducted as a prospective cohort and was completed with 19 patients. Three-step tympanometry (basal, Toynbee, Valsalva), dynamic slow-motion video endoscopy, and the Eustachian Tube Dysfunction Questionnaire-7 (ETDA-7) were applied to the patients preoperatively before bariatric surgery and in the postoperative 6th month.

Acoustic parameter changes after bariatric surgery.

Objective: To investigate the acoustic parameter changes after weight loss in bariatric surgery patients.

Materials And Methods: This prospective, longitudinal study was conducted with 15 patients with planned bariatric surgery, who were evaluated pre-operatively and at 6 months post-operatively. Fundamental frequency (F0), Formant frequency (F1, F2, F3, and F4), Frequency perturbation (Jitter), Amplitude perturbation (Shimmer) and Noise-to-Harmonics Ratio (NHR) parameters were evaluated for /a/, /e/, /i/, /o/, and /u/ vowels.
