and evaluation of the nutritional value of various hydrolyzed feather meals and comparison of their effect on performance and carcass characteristics of broilers.

In the current study, the nutritional value of various hydrolyzed feather meals (HFM) was investigated in two separate experiments (an and an experiment). The experiment was based on a completely randomized design with five replications and seven treatments including (1) Raw feather meal (RFM), (2) HFM by autoclave (Au-HFM), (3) Fermented feather meal (FFM) by (Bl-FFM), (4) FFM by (Bs-FFM), (5) FFM by (An-FFM), (6) FFM by  +  +  (Co-FFM), and (7) HFM by an enzyme (En-HFM). The highest pepsin-pancreatin and apparent ileal CP digestibility were observed in Co-FFM, and the lowest amount belonged to RFM (P < 0.

Feather meal processing methods impact the production parameters, blood biochemical indices, gut function, and hepatic enzyme activity in broilers.

This study investigated the effects of feather meal (FM) processing methods on production parameters, blood biochemical indices, intestinal morphology, digestive and hepatic enzyme activities, and gastrointestinal tract pH and microflora of broilers. A total of 480-d-old male broilers were used for 42 d in a completely randomized design with eight treatments and five replicates (12 chicks/replicate). Treatments were 1) a control diet (without FM), 2) a diet containing 4% raw FM (RFM), 3) a diet containing 4% processed FM (PFM) by autoclave (Au-PFM), 4) a diet containing 4% fermented FM (FFM) by Bacillus licheniformis (Bl-FFM), 5) a diet containing 4% FFM by Bacillus subtilis (Bs-FFM), 6) a diet containing 4% FFM by Aspergillus niger (An-FFM), 7) a diet containing 4% FFM by B.

An environmentally friendly method for extraction of cobalt and molybdenum from spent catalysts using deep eutectic solvents (DESs).

There has been a substantially increasing demand for energy critical elements (ECEs) in recent years as energy-related technology has advanced rapidly. Spent catalysts are known as potential sources of ECCs such as Ni, Co, Mo, W, V, and rare earth elements. This study developed a novel environmentally friendly process for recovering cobalt and molybdenum from spent hydroprocessing catalysts using deep eutectic solvents (DESs).

Tetrathiafulvalene-Benzothiadiazole: A Metal-Free Photocatalyst for Hydrogen Production.

In this work, a series of hybrid tetrathiafulvalene-benzothiadiazole (TTF-BTD) are designed and applied as a metal-free photocatalyst for hydrogen production, particularly under visible light irradiation. Density functional theory calculations are used to shed light on the photophysical properties observed in the various TTF-BTD derivatives and investigated by the obtained data. Because band gap engineering has normally been used as an effective approach, we studied the effect of the various functional groups on the band gap to set a favorable band alignment with photocatalysts.

Relationship between sperm quality and total fertilization failure in intracytoplasmic sperm injection and in vitro fertilization cycles: A cross-sectional study.

Background: Total fertilization failure (TFF) is associated with essential mechanistic and cellular events.

Objective: The present study is a comprehensive examination of detrimental effects with well-known assays for predicting TFF in conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles.

Materials And Methods: Semen parameters of 90 men, including 60 cases who had experienced IVF/ICSI failure and a control group of 30 individuals, were evaluated.

Effect of brain-derived neurotrophic factor (BDNF) on sperm quality of normozoospermic men.

The neurotrophin family of proteins and their receptors act as important proliferative and pro-survival factors in differentiation of nerve cells and are thought to play key roles in the development of reproductive tissues and normal function of spermatozoa. The objective of the present study was to evaluate the effect of Brain-Derived Neurotrophic Factor (BDNF) on the sperm viability and motility, lipid peroxidation (LPO), mitochondrial activity and concentration of leptin, nitric oxide (NO) and insulin in normozoospermic men. Semen samples from 20 normozoospermic men were divided into three groups: (i) control, (ii) BDNF and (iii) BDNF + K252a.

Enhanced Chiral Discriminatory van der Waals Interactions Mediated by Chiral Surfaces.

We predict a discriminatory interaction between a chiral molecule and an achiral molecule which is mediated by a chiral body. To achieve this, we generalize the van der Waals interaction potential between two ground-state molecules with electric, magnetic, and chiral response to nontrivial environments. The force is evaluated using second-order perturbation theory with an effective Hamiltonian.

Body-assisted van der Waals interaction between excited atoms.

We present a formula for the body-assisted van der Waals interaction potential between two atoms, one or both being prepared in an excited energy eigenstate. The presence of an arbitrary arrangement for a material environment is taken into account via the Green function. The resulting formula supports one of two conflicting findings recorded.
