The effect of various feeding strategies was evaluated on growth performance and biochemical parameters in two sizes of Siberian sturgeon (465.75 ± 11.18 and 250.40 ± 12 g) during 45 days. Fish were distributed into six experimental treatments including large fish with satiation feeding (LA), small fish with satiation feeding (SA), large fish with 50% satiation feeding (LR), small fish with 50% satiation feeding (SR), large starved fish (LS), and small starved fish (SS). Differences in final weight between LA and LR treatments were not noticeable, whereas SA and SR treatments showed significant differences...

PURPOSE: Induction of labor is a common practice in obstetrics. In recent years, a newer ultrasonographic parameter called the uterocervical angle (UCA) has been identified as a predictive tool for births. Our purpose is to investigate the role of UCA in predicting successful induction of labor. METHODS: The nulliparous term pregnancies (n:150) were grouped into successful/failed inductions of labor based on their progress into the active phase of labor after the administration of prostaglandin E2 (dinoprostone)...

PURPOSE: Irinotecan (CPT-11) in combination with 5-fluorouracil (5FU) is widely used in the treatment of colorectal cancer. We assessed potential clinical variables that may predict toxicity and more specifically the role of UGT1A1 polymorphisms associated with irinotecan toxicity. We used data from the PETACC3 trial, which randomised patients in adjuvant setting to 6 months of leucovorin (LV) and 5FU (LV5/FU2) or LV5/FU2 + irinotecan. PATIENTS AND METHODS: Clinical and toxicity data were available for 2982 patients, DNA was available for 1200 (40%) of these patients...

The treatment of mandibular condyle fractures has been the subject of considerable discussion, especially whether open or closed treatment should be used. There is a need for practical,evidence-based guidelines, and both objective and subjective parameters should be measured. To date, fewstudies have considered clinically relevant subjective parameters. This study was performed to evaluate the outcomes of the treatment of condylar fractures using the Mandibular Function Impairment Questionnaire (MFIQ) and the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and to compare the outcomes of open and the closed treatment...

OBJECTIVE: Mesenchymal stem/stromal cells derived from human term placentas (PMSCs) are novel therapeutic agents and more topical than ever. Here we evaluated the effects of three types of PMSCs on wound healing in an in vivo mouse model: Amnion-derived MSCs (AMSCs), blood vessel-derived MSCs (BV-MSCs) from the chorionic plate and Wharton's jelly-derived MSCs (WJ-MSCs) from the umbilical cord. METHODS: We topically applied PMSCs onto skin wounds in mice using the dermal substitute Matriderm® as carrier and evaluated wound healing parameters...

All physicians are likely to encounter gender diverse patients, and some of these patients require medically necessary surgical procedures. It is optimal for surgeons to collaborate with other providers who interact with this patient population. Primary care physicians initiate treatment with consultation from mental health professionals and refer to surgeons when necessary. Best practices consist of preventative care, hormone therapy induction when indicated, monitoring of all health parameters, and continuing care medically and postoperatively...

Pollution risk from the discharge of industrial waste or accidental spills during transportation poses a considerable threat to the security of rivers. The ability to quickly identify the pollution source is extremely important to enable emergency disposal of pollutants. This study proposes a new approach for point source identification of sudden water pollution in rivers, which aims to determine where (source location), when (release time) and how much pollutant (released mass) was introduced into the river...

In mice living under normal animal house conditions, the brown adipocytes in classical brown adipose tissue depots are already essentially fully differentiated: UCP1 mRNA and UCP1 protein levels are practically saturated. This means that any further recruitment - in response to cold exposure or any other browning agent - does not result in significant augmentation of these parameters. This may easily be construed to indicate that classical brown adipose tissue cannot be further recruited. However, this is far from the case: the capacity for further recruitment instead lies in the ability of the tissue to increase the number of brown-fat cells, a remarkable and highly controlled physiological recruitment process...

PURPOSE: The two distinct dose computation paradigms of Boltzmann Equation Solvers and Monte Carlo simulation both promise in principle maximum accuracy. In practice, clinically acceptable calculation times demand approximations and numerical short-cuts on one hand, and modelling the beam characteristics of a real linear accelerator to the required accuracy on the other. A thorough benchmark of both algorithm types therefore needs to start with beam modelling, and needs to include a number of clinically challenging treatment plans...

A cost-effective microporous polymer was synthesized using cheap monomer and catalyst via one-step Scholl-coupling reaction, and its chemical, morphological characteristics and pore structure were investigated. The as-synthesized polymer with large surface area and narrow pore distribution (centered in 1.2 nm) was prepared as a fiber coating for solid-phase microextraction (SPME). Headspace SPME was used for the extraction of the light aromatic compounds, e.g. benzene, toluene, ethylbenzene, m-xylene, naphthalene and acenaphthene...

Cardiogenic shock is a clinical syndrome characterized by low cardiac output and sustained tissue hypoperfusion resulting in end-organ dysfunction and death. In-hospital mortality rates range from 50% to 60%. Urgent diagnosis, timely transfer to a tertiary or quaternary medical facility with critical care management capabilities and multidisciplinary shock teams is a must to increase survival. Aggressive, hemodynamically guided medical management with careful monitoring of clinical and hemodynamic parameters with timely use of appropriate mechanical circulatory support devices is often necessary...

An eleven weeks feeding trial was conducted to determine the effects of different levels of dietary soybean lecithin (SBL) on growth performance, blood chemistry and immunity in juvenile stellate sturgeon (Acipenser stellatus). Fish were fed seven isoproteic (44% crude protein) and isolipidic (17% crude fat) diets containing graded levels of SBL: 0 (control), 1, 2, 4, 6, 8 and 10%. Results showed that dietary SBL supplementation significantly improved the final body weight (BW) and weight gain (WG). Fish fed 6% SBL showed the highest BW and WG values in comparison to fish fed the control diet (P < 0...

Dislocation imaging using transmission electron microscopy (TEM) has been an invaluable tool for characterizing crystallographic defects in metals. Compared to conventional TEM imaging, diffraction contrast imaging scanning transmission electron microscopy (DCI STEM) with appropriate setting can provide better defect contrast with almost negligible bend contour artifacts, enabling more effective analysis of dislocation structures. Here, we investigated why STEM can suppresses bend contour, and how dislocation contrast behaves along with different STEM imaging parameters...

BACKGROUND: Studies of vaccine effectiveness (VE) rely on accurate identification of vaccination and cases of vaccine-preventable disease. In practice, diagnostic tests, clinical case definitions and vaccination records often present inaccuracies, leading to biased VE estimates. Previous studies investigated the impact of non-differential disease misclassification on VE estimation. METHODS: We explored, through simulation, the impact of non-differential and differential disease- and exposure misclassification when estimating VE using cohort, case-control, test-negative case-control and case-cohort designs...

The purpose of our study was a comparative analysis of the effect of dentures from various materials on the immunological and redox-dependent homeostasis of the oral cavity. We studied 60 patients with removable dentures made based on plastics Prothyl Hot, Vertex BasiQ 20 (differing by polymerization regime) and elastic thermoplastic polymer Perflex Flexi Nylon. The control group consisted of 15 volunteers with a practically healthy oral cavity, who did not use dentures. Saliva collected on an empty stomach in a glass tube without the use of a stimulator before the establishment of a denture and 3 days and 1 month after...

Obesity can negatively impact intestinal homeostasis, and increase colon cancer risk and related mortality. Thus, given the alarmingly high rates of obesity in the US and globally, it is critical to identify practical strategies that can break the obesity-cancer link. Walnuts have been increasingly recognized to mitigate cancer risk, and contain many bioactive constituents with antioxidant and anti-inflammatory properties that could potentially counteract pathways thought to be initiators of obesity-related cancer...

The level of pain perception is correlated with the magnitude of pain-evoked brain responses, such as laser-evoked potentials (LEP), across trials. The positive LEP-pain relationship lays the foundation for pain prediction based on single-trial LEP, but cross-individual pain prediction does not have a good performance because the LEP-pain relationship exhibits substantial cross-individual difference. In this study, we aim to explain the cross-individual difference in the LEP-pain relationship using inter-stimulus EEG (isEEG) features...
