Aim: Natural orifice specimen extraction surgery (NOSES) has gained significant importance in treating cancers. The current study is a meta-analysis that aimed to assess the short-term efficacy and long-term prognostic impact of NOSES and conventional laparoscopic (CL) surgery in the treatment of colorectal cancer (CRC).
Method: Published reports in several medical databases up to February 2024 were searched and information pertinent to outcomes of NOSES and CL in retrospective and randomized studies to treat CRC was collected.

The bi-transition-metal interstitial compounds (BTMICs) are promising for water electrolysis. The previous BTMICs are usually composed of irregular particles. Here, this work shows the synthesis of novel 1D CoMoC-based heterojunction nanowires (1D Co/CoMoC) with diameters about 50 nm and a length-to-diameter ratio about 20 for efficient water electrolysis.

Background: The infections of bacterial origin represent a significant problem to the public healthcare worldwide both in clinical and community settings. Recent decade was marked by limiting treatment options for bacterial infections due to growing antimicrobial resistance (AMR) acquired and transferred by various bacterial species, especially the ones causing healthcare-associated infections, which has become a dangerous issue noticed by the World Health Organization. Numerous reports shown that the spread of AMR is often driven by several species-specific lineages usually called the 'global clones of high risk'.

The number of microglia cells and astrocytes in layer V of the cerebral cortex was estimated on day 7 after damage caused by a unilateral focal traumatic brain injury of the left hemisphere sensorimotor cortex. Quantitative assessment was performed by counting immunocytochemically stained microglia cells (Iba1 marker) and activated astrocytes (GFAP) at different distances from the lesion site. Activation of microglial and astroglial cells was observed not only in the marginal zone of the lesion of the left hemisphere, but also in the intact hemisphere.

The highest hemolytic activity of M. morganii cultivated in urine with low urea concentration (23 and 82 mmol/liter) was observed between 3rd and 4th hours of post-inoculation, while in urine with standard urea level (117 mmol/liter), the activity was observed at 5th hour of post-inoculation.

Micromycetes from the genus Alternaria are commonly found in plant food raw materials, and their produced emerging mycotoxins (EMT) pose a risk to human health. Based on polyphase taxonomy, we studied the species composition of the Alternaria spp. population in samples of Russian grain and berries; non-toxinogenic species of Alternaria of the Infectoriae section and toxinogenic species of the Alternaria section were found.

MSN particles, neither uncoated nor coated with calcium alginate, induced spontaneous platelet aggregation when added to platelet-rich plasma, but significantly enhanced ADP-induced platelet aggregation. Subcutaneous administration of uncoated and calcium alginate-coated MSN resulted in increased maximum size and rate of platelet aggregate formation 1 day post-injection.

We conducted a comparative study of the mammary gland microbiota in female Wistar rats and the microbiota associated with breast cancer (BC) induced by the administration of N-methyl-N-nitrosourea, after surgical treatment, photodynamic therapy (PDT), and chemotherapy (CT). Selective nutrient media and a smear-fingerprint technique were used to study the microbiota. Staphylococcus, Streptococcus, and Lactobacillus were found in the mammary glands of intact rats.

It has been found that by behavioral and hemodynamic parameters the physiological activity of angiotensin II (Ang II) in combination with mLDL is considerably modified due to weakening of its diuretic effect and the inversion of hypertensive and tachyarrhythmic effects. Atherosclerosis is a long-term pathological process, so a single administration of artificially synthesized Ang I-mLDL complexes can be considered a model of the first contact of the body with pathogenic factors.

FoxP3 T-regulatory (Treg) lymphocytes and cytokine production by cells from the stromal vascular fraction (SVF) of epicardial (EAT) and thymus (TAT) adipose tissue of 42 patients with chronic coronary heart disease (CHD) were studied. In the SVF of TAT in patients with Gensini Score (GS)≥74 (the most severe atherosclerosis), the production of IL-1β, TNF, IL-4, and IFNγ was higher, while FoxP3 translocation into the nucleus was lower than in patients with GS<74. The GS index directly correlated with the production of IL-4, IL-1β, and TNF by cells of the SVF of TAT, and inversely - with the production of TNF, IL-17, and IL-10 by cells of the SVF of EAT.

The effect of optical stimulation at a frequency of 10 Hz (OS) on temporal parameters of sensorimotor activity in healthy subjects (n=32) was studied. The expression of the activation response was determined by the ratio of spectral power values (SPα2, μV) of the high frequency (10-13 Hz) subrange of the α-rhythm of the initial EEG with closed and opened eyes and the frequency of the maximum α-peak (IAPF). A test for simple motor reaction time was performed under normal and OS conditions.

The optimal balance of the intestinal microbiota is considered to be an essential part of the human body that affects many metabolic processes. However, the exact role of the gut microbiota in metabolism is still not fully understood. To investigate the metabolic role of gut microbiota, the content of short-chain fatty acids and tryptophan metabolites was studied in mice with sodium dextran sulfate-induced colitis.

The expression of somatostatin receptors (SSTRs) of types 1, 2, and 5 was studied in the small intestine of rats from different age groups (1, 10, 20, 30, 60 days, and 2-year-old) using Western blotting. The expression of SSTR1, SSTR2, and SSTR5 increased in the first 30 days of life, but decreased in older rats compared to 2-month-old animals. These findings suggest that there is differential expression of SSTRs during age-related development of the small intestine.

Reprogramming of T cells was carried out using a MEK inhibitor and a PD-1 blocker; the targeting of rT cells to tumor cells was achieved by preincubation with LLC cell lysate. It was shown that the antitumor effect of rT cells was based on apoptosis of tumor cells.

Purpose: This study explores the use of heart rate variability (HRV) analysis, a noninvasive technique for assessing the autonomic nervous system, by applying nonlinear dynamics and chaos theory to detect chaotic behavior in RR intervals and assess cardiovascular health.
Methods: Employing the "System Analysis of Heart Rate Dynamics" (SADR) program, this research combines chaos analysis with the short-time Fourier transform to assess nonlinear dynamic parameters in HRV. It includes constructing phase portraits in Takens space and calculating measures of chaos to identify deterministic chaos indicators.

Receptor Interacting Serine/Threonine Kinase 1 (RIPK1) is widely expressed and integral to inflammatory and cell death responses. Autosomal recessive RIPK1-deficiency, due to biallelic loss of function mutations in RIPK1, is a rare inborn error of immunity (IEI) resulting in uncontrolled necroptosis, apoptosis and inflammation. Although hematopoietic stem cell transplantation (HSCT) has been suggested as a potential curative therapy, the extent to which disease may be driven by extra-hematopoietic effects of RIPK1-deficiency, which are non-amenable to HSCT, is not clear.

Accurate estimation of interfacial tension (IFT) between nitrogen and crude oil during nitrogen-based gas injection into oil reservoirs is imperative. The previous research works dealing with prediction of IFT of oil and nitrogen systems consider synthetic oil samples such n-alkanes. In this work, we aim to utilize eight machine learning methods of Decision Tree (DT), AdaBoost (AB), Random Forest (RF), K-nearest Neighbors (KNN), Ensemble Learning (EL), Support Vector Machine (SVM), Convolutional Neural Network (CNN) and Multilayer Perceptron Artificial Neural Network (MLP-ANN) to construct data-driven intelligent models to predict crude oil - nitrogen IFT based upon experimental data of real crude oils samples encountered in underground oil reservoirs.

Copper(II) oxide nanoparticles (CuO NPs) are used in different industries and agriculture, thus leading to their release to the environment, which raises concerns about their ecotoxicity and biosafety. The main toxicity mechanism of nanometals is oxidative stress as a result of the formation of reactive oxygen species caused by metal ions released from nanoparticles. Bacterial biofilms are more resistant to physical and chemical factors than are planktonic cells due to the extracellular polymeric matrix (EPM), which performs a protective function.
