L K Schüller, I Michaelis, W Heuwieser
The objective of this study was to investigate the impact of heat stress on the expression of estrus signs and follicular diameter at the day of estrus in dairy cows under farm conditions. Cows reported in estrus (i.e., by an automated activity monitoring system or by the herd manager) were examined by a veterinarian. Uterine contractility and the largest diameter of all ovarian structures was determined by transrectal palpation and ultrasonography, respectively. The amount of estrus discharge, mounting traces and the color of the vaginal mucosa were determined in an external examination and scored on 3-point scales...

The majority of non-protein-coding RNAs present in eukaryotic cells comprises rRNAs, tRNAs and U6 snRNA that are involved in protein biosynthesis and are synthesized by DNA-dependent-RNA polymerase I and III. The transcription cycle (initiation, elongation and termination) has similar principles in all three nuclear RNA polymerases with specific features that are reflected back in their structures. Recently, owing to the 'resolution revolution' in electron cryo-microscopy, there has been a significant advancement in the understanding of these molecular machines...

BACKGROUND: Achilles tendon injuries are common in sports, including football. The purpose of this study was to determine (1) return-to-sport rate in National Football League (NFL) players following Achilles tendon repair, (2) postoperative career length and games per season, (3) pre- and postoperative performance, and (4) postoperative performance compared with control players matched by position, age, years of experience, and performance. METHODS: Publicly available records were used to identify NFL players who underwent Achilles tendon repair and matched controls were identified...

Burst-firing in thalamic neurons is known to play a key role in mediating thalamocortical (TC) oscillations that are associated with non-REM sleep and some types of epileptic seizure. Within the TC system the primary output of GABAergic neurons in the reticular thalamic nucleus (RTN) is thought to induce the de-inactivation of T-type calcium channels in thalamic relay (TR) neurons, promoting burst-firing drive to the cortex and the propagation of TC network activity. However, RTN neurons also project back onto other neurons within the RTN...

Globular proteins, such as cytochrome c (cyt c), display an organized native conformation, maintained by a hydrogen bond interaction network. In the present work, the structural interrogation of kinetically trapped intermediates of cyt c was performed by correlating the ion-neutral collision cross section (CCS) and charge state with the starting solution conditions and time after desolvation using collision induced activation (CIA), time resolved hydrogen/deuterium back exchange (HDX) and trapped ion mobility spectrometry - mass spectrometry (TIMS-MS)...

The lineage of the Bar-backed Partridge (Arborophila brunneopectus) was investigated to determine the phylogenetic relationships within Arborophila as the species is centrally distributed within an area covered by the distributions of 22 South-east Asian hill partridge species. The complete mitochondrial genome (mitogenome) of A. brunneopectus was determined and compared with four other hill partridge species mitogenomes. NADH subunit genes are radical in hill partridge mitogenomes and contain the most potential positive selective sites around where variable sites are abundant...

BACKGROUND: For medical teams, one of the main objectives of rehabilitation for people with chronic low back pain is adherence to physical activity (PA). OBJECTIVE: The objective of this study was to identify PA barriers and facilitators in this population. METHODS: This qualitative study included 4 discussion groups and 16 semi-structured interviews conducted among people with non-specific chronic low back pain who were involved in a specific rehabilitation program or seen in primary care settings...

STUDY DESIGN: Economic evaluation alongside a randomized trial of cognitive-behavioral therapy (CBT) and mindfulness-based stress reduction (MBSR) versus usual care alone (UC) for chronic low-back pain (CLBP). OBJECTIVE: Determine the one-year cost-effectiveness of CBT and MBSR compared to UC. SUMMARY OF BACKGROUND DATA: CLBP is expensive in terms of healthcare costs and lost productivity. Mind-body interventions have been found effective for back pain, but their cost-effectiveness is unexplored...

OBJECTIVE: This study examines the impact of an insurance-mandated change in formulation of buprenorphine/naloxone (BNX) for patients with opioid use disorder treated in a primary care clinic. METHODS: A retrospective cohort study was conducted to determine the proportion of patients who were switched back to the previous BNX formulation and rates of aberrant urine drug tests for the 3 months before and 3 months after a mandated change in BNX from the sublingual film to the rapidly dissolving tablet (BNX-RDT)...

Long- and short-term adverse outcomes in hemodialysis (HD) have been associated with intradialytic hypotension, a common HD complication and significant cause of morbidity. It has been suggested that knowledge of absolute blood volume (ABV) could be used to significantly improve treatment outcomes. Different dilution-based protocols have been proposed for estimating ABV, all relying on the classic mono-exponential back-extrapolation algorithm (BEXP). In this paper, we introduce a dialysate dilution protocol and an estimation algorithm based on a variable-volume, two-compartment, intravascular blood water content kinetic model (VVKM)...

Objective To assess the efficacy of an exercise program towards reducing back pain in pregnant women. Methods In this prospective control study, 145 low risk pregnant women who scored more than 20 for functional limitation assessment were recruited. The severity of back pain was assessed using the visual analoque scale (VAS) and the functional limitation was assessed using the Oswestry disability questionnaire (ODQ). All participants were informed of back care measures and provided with Paracetamol as an adjunct analgesia...

Vice Versa, published in Los Angeles from 1947-1948 and regarded as the first lesbian periodical in the United States, was authored and edited by Lisa Ben (anagram for "lesbian"). While Vice Versa is lauded for inspiring later lesbian publications, little scholarship has analyzed the magazine's contents. Queer rhetorical analysis allows me to demonstrate the integral role Vice Versa played in counteracting cultural and medical classifications of lesbians during the 1940s. Through an analysis of Vice Versa's book and movie reviews, an editorial, and creative writing, this article analyzes the way Ben uses queer rhetoric to turn narratives of medical and psychological deviancy and inferiority into a means for empowerment and community building...

The role that nutrition plays in cancer development and treatment has received considerable attention in recent decades, but it still engenders considerable controversy. Within the cancer research and especially the clinical community, for example, nutritional factors are considered to play, at best, a secondary role. The role of nutrition in cancer development was noted by authorities as far back as the early 1800s, generally under the theory that cancer is "constitutional" in its origin, implying a complex, multifactorial, multistage etiology...

BACKGROUND: Spinal cord stimulation (SCS) is an effective therapy to reduce pain in patients that suffer from failed back surgery syndrome (FBSS). In order to inform patients optimally prior to this therapy, knowing their expectations is crucial. METHODS: Thirteen patients suffering from FBSS and scheduled for SCS were interviewed, using a semi-structured protocol. Patients were interviewed either at home or at their treating hospital. Data from these interviews were analyzed using directed content analysis...

Sortilin-1, a receptor of the VPS10p family, has been associated with cardiovascular disease in genome-wide association studies. It is implicated in lipoprotein metabolism, secretion of proprotein convertase subtilisin/kexin type 9 (PCSK9) and secretion of inflammatory cytokines. However, its own regulation remains unclear. Chronic inflammation is a hallmark of atherosclerosis and absence of regulatory T (Treg) cells is associated with reduced protein expression of sortilin-1 in the liver. Therefore, we postulated that mediator(s) of inflammation known to be downregulated by regulatory T cells may modulate sortilin-1 expression...
