Sericin-Enriched Rabbit Semen Preservation: Implications for Short-Term Storage Quality and Fertility at 4 or 15 °C.

The influence of sericin supplementation and chilling temperatures (4 and 15 °C) on the short-term storage quality and fertility of rabbit semen was assessed over 72 h of storage. In experiment 1, pooled semen (five replications) was diluted to a concentration of 50 M mL, and assigned to control, 0.1%, and 0.

Comparative efficiency of novel laparoscopic and routine vaginal inseminations with cryopreserved semen in rabbits.

Laparoscopic artificial insemination technique (LAI) is described to overcome reduced fertility problems in sheep artificial insemination (AI) programmes with frozen semen. Later on, this technology was modified for endangered non-domestic cats to deposit low quality or reduced number of sperm cells hardly obtained by electro-ejaculation into the oviduct. This technique by passes the complex structure of cervix and efficiently transfers the sperm cells to the point of fertilization.

Evaluation of haemodynamic changes of uterine arteries using Doppler ultrasonography during different stages of pregnancy in Bos indicus cows.

The objectives of the study were to evaluate haemodynamic changes and their relationships among ipsilateral (IPS) and contralateral (CONT) uterine arteries (UA) during different stages of pregnancy in Bos indicus cows. Multiparous pregnant cows (n = 40) having a gestation length 30.47 ± 0.

Silk protein sericin pretreatment enhances osmotic tolerance and post-thaw sperm quality but reduces the ability of sperm cells to undergo in vitro induced acrosome reaction in rabbit.

Effect of sericin pretreatment of sperm cells on the osmotic tolerance, ability to undergo acrosome reaction induced by calcium ionophore (CI), heparin (H) or lysophosphatidylcholine (LPC), post-thaw sperm quality and in vivo fertility was evaluated in four successive experiments in rabbit. In experiment 1, fresh semen was pretreated with sericin (0, 0.1% or 0.

Ultrasonographic evaluation of feto-placental tissues at different intrauterine locations in rabbit.

The main purpose of examining multiparous species with real-time ultrasonography is to determine the gestational age and make various fetal measurements for early diagnosis of growth anomalies and sibling mismatches. This study investigated changes in fetometric measurements, obstetric Doppler indices and placental image analysis results based on gestational age and fetal location in fetuses located cranially and caudally between 16 and 24 days gestation in 22 healthy pregnant New Zealand rabbits. The first study group consisted of fetuses positioned at the cranial end (n = 22) while the second group consisted of fetuses positioned at the caudal end (n = 22) in each pregnancy.

Characterization of phytochemical components of Ferula halophila extracts using HPLC-MS/MS and their pharmacological potentials: a multi-functional insight.

The inhibitory action of F. halophila extracts (acetone, chloroform, and methanol) against key enzymes linked to diabetes (α-amylase, α-glucosidase), cognitive functions (acetyl cholinesterase (AChE), butyryl cholinesterase (BChE)), and hyperpigmentation (tyrosinase) was assessed. The mutagenic/antimutagenic activities were assessed and the phytochemical profile established by HPLC-MS/MS.

Biological effects and chemical characterization of Iris schachtii Markgr. extracts: A new source of bioactive constituents.

This study gathers information about the effects of different extracts (methanol and water) from rhizomes and aerial parts of Iris schachtii on selected enzymes (cholinesterases, alpha-amylase and alpha-glucosidase, tyrosinase and lipase) as well as of their antioxidant capacities and antimutagenic properties in relation with their phenolic composition. The chemical composition was assessed by determining total phenolic and flavonoid content as well as individual phenolic compounds by HPLC-DAD. Moreover, antioxidant abilities of the investigated extracts were tested by using different assays including free radical scavenging (DPPH and ABTS), reducing power (CUPRAC and FRAP), phosphomolybdenum and metal chelating, overall rhizomes being indicated as a superior source of antioxidant compounds.

Chemical and biological insights on Cotoneaster integerrimus: A new (-)- epicatechin source for food and medicinal applications.

Background: The Cotoneaster species are widely used as traditional purposes in different countries including Turkey.

Purpose: The study was performed to evaluate the biological and chemical profile of two extracts (methanol (T-Me; F-Me) and water (T-W; F-W)) from two parts (twigs and fruits) of Cotoneaster integerrimus.

Materials And Methods: Antioxidant (free radical scavenging (DPPH), reducing power (CUPRAC and FRAP), phosphomolybdenum and metal chelating), enzyme inhibitory (cholinesterase, tyrosinase, α-amylase and α-glucosidase), antimicrobial (standard microorganisms and methicillin-resistant Staphylococcus aureus isolates (MRSA)) and mutagenic/antimutagenic effects (by Ames assay) were tested for biological profile.

Assessment of antimutagenic action of Celtis glabrata Steven ex Planch. (Cannabaceae) extracts against base pair exchange and frame shift mutations on Salmonella typhimurium TA98 and TA100 strains by Ames test.

Context: Celtis glabrata is used in Turkey for the treatment of various health disorders.

Objective: The acetone, chloroform, ethanol, and methanol extracts of C. glabrata leaf, fruit, and seed were investigated to evaluate their antimutagenic activities.

Two Ganoderma species: profiling of phenolic compounds by HPLC-DAD, antioxidant, antimicrobial and inhibitory activities on key enzymes linked to diabetes mellitus, Alzheimer's disease and skin disorders.

This work reports the antioxidant, antimicrobial, and inhibitory effects of methanol and water extracts from Ganoderma applanatum (GAM: methanol extract and GAW: water extract) and G. resinaceum (GRM: methanol extract and GRW: water extract) against cholinesterase, tyrosinase, α-amylase and α-glucosidase. The total phenolics, flavonoids contents, and HPLC profile of phenolic components present in the extracts, were also determined.

Survey of phytochemical composition and biological effects of three extracts from a wild plant (Cotoneaster nummularia Fisch. et Mey.): a potential source for functional food ingredients and drug formulations.

This study was focused on the analysis of the phenolic content, antioxidant, antibacterial, anti-cholinesterase, anti-tyrosinase, anti-amylase and anti-glucosidase activity of three solvent extracts from Cotoneaster nummularia. Moreover, water extract was tested in terms of mutagenic/anti-mutagenic effects. The antioxidant activities of these extracts were evaluated by DPPH, ABTS, O2, metal chelating, phosphomolybdenum, β-carotene/linoleic acid, ferric and cupric reducing power assays.

Improving collection efficiency through remote monitoring of charity assets.

Collection costs associated with servicing a major UK charity's donation banks and collecting unsold goods from their retail shops can account for up to 20% of the overall income gained. Bank and shop collections are commingled and are typically made on fixed days of the week irrespective of the amounts of materials waiting to be collected. Using collection records from a major UK charity, this paper considers what vehicle routing and scheduling benefits could accrue if bank and shop servicing requirements were monitored, the former using remote sensing technology to allow more proactive collection scheduling.

Characterization of Klebsiella pneumoniae strains isolated from urinary tract infections: detection of ESBL characteristics, antibiotic susceptibility and RAPD genotyping.

In this study, a hundred Klebsiella pneumoniae strains isolated from urinary tract infections were evaluated in terms of genotyping, susceptibility to certain antibiotics and detection of extended spectrum of beta lactamase (ESBL) production. The random amplified polymorphic DNA (RAPD-PCR) method was used to identify the genetic differentiation of K. pneumoniae isolates.
