Aquaporin 4 in the chicken oviduct during a pause in laying induced by food deprivation.

In the present study we hypothesize that aquaporin 4 (AQP4) expression in the chicken oviduct would change during a pause in egg laying that was induced by fasting. Accordingly, the aim of this investigation was to examine the AQP4 mRNA and protein expression, and immunolocalization in the chicken oviduct during the course of regression. The experiment was carried out on laying hens subjected to a pause in laying that was induced by food deprivation for 5 days. Control hens were fed ad libitum. The birds were sacrificed on day 6 of the experiment and all segments of the oviduct were isolated, including the infundibulum, magnum, isthmus, shell gland, and vagina. Subsequently, the gene and protein expressions of AQP4 in the tissues were tested by real-time PCR and Western blot, respectively. The relative mRNA expression of AQP4 was the highest in the infundibulum and vagina and the lowest, and least detectable, in the magnum. The level of AQP4 protein was the highest in the infundibulum and the lowest in the magnum. Fasting resulted in a decrease of the AQP4 mRNA expression (P<0.001) in the infundibulum, a decrease in protein abundance (P<0.01) in the shell gland, and an increase in protein level (P<0.001) in the vagina. Immunohistochemistry demonstrated tissue- and cell-dependent localization of AQP4 protein in the oviductal wall. The intensity of staining was as follows: the infundibulum > shell gland > vagina ≥ isthmus ≫ magnum. In the control hens, the immunoreactivity for AQP4 in the vagina was similar, whereas in other oviductal segments, the immunoreactivity was stronger when compared with the chickens subjected to a pause in laying. In summary, these findings suggest that the AQP4 is an essential protein involved in the regulation of water transport required to create a proper microenvironment for fertilization and egg formation in the hen oviduct.
Ovariectomy uncouples lifespan from metabolic health and reveals a sex-hormone-dependent role of hepatic mTORC2 in aging

Inhibition of mTOR (mechanistic Target Of Rapamycin) signaling by rapamycin promotes healthspan and longevity more strongly in females than males, perhaps because inhibition of hepatic mTORC2 (mTOR Complex 2) specifically reduces the lifespan of males. Here, we demonstrate using gonadectomy that the sex-specific impact of reduced hepatic mTORC2 is not reversed by depletion of sex hormones. Intriguingly, we find that ovariectomy uncouples lifespan from metabolic health, with ovariectomized females having improved survival despite paradoxically having increased adiposity and decreased control of blood glucose levels. Further, ovariectomy unexpectedly promotes midlife survival of female mice lacking hepatic mTORC2, significantly increasing the survival of those mice that do not develop cancer. In addition to identifying a sex hormone-dependent role for hepatic mTORC2 in female longevity, our results demonstrate that metabolic health is not inextricably linked to lifespan in mammals, and highlight the importance of evaluating healthspan in mammalian longevity studies.
Radiation exposure exerts its adverse effects on sperm maturation through estrogen-induced hypothalamohypophyseal axis inhibition in rats

Irradiation has adverse effects on reproductive aspects such as spermatogenic cell population and cell malformation, leading to reduced sperm count and non-viable spermatozoa. This has overshadowed possible effects of radiation exposure on biochemical environment throughout the epididymis and the viability of spermatozoa that appeared morphologically normal. The effects of radiation exposure on sperm quality were evaluated through mating trials and assessment of the cauda epididymal sperm motility. Sprague Dawley rats with body mass of 300–400 g were selected at random. Two experimental groups received acute 6°Co γ-radiation doses of 3.5 and 6.0 Gy, respectively. Data were collected 2, 7, 14, 21, 28 and 35 days post-irradiation. Each male was housed with a non-irradiated super-ovulated female during mating trials. Cauda epididymal sperm motility was assessed with the CASMA. Hormone analyses were carried through chemiluminescence diagnostic tests to determine the endocrine status. Results suggest that irradiation causes an overproduction of estrogens, which suppresses the hypothalamic-pituitary axis and inhibits LH and FSH secretions. Both LH and FSH deficiencies have negative effects on the testicular index and local reproductive hormones. Elevated estrogen levels influenced the epididymal internal milieu negatively, resulting in rigid, flagella bending sperm tail, impaired progressive movement of the spermatozoa and hence infertility
Rehabilitative of COVID-19 patients with acute lower extremity Ischemia and amputation.

OBJECTIVE To evaluate the clinical characteristics and rehabilitation management of patients who undergo amputation for COVID-19-associated coagulopathy. METHODS Clinical and laboratory data for 3 patients were analysed and their rehabilitative management discussed. RESULTS The medical records of 3 patients who had undergone amputation due to acute lower extremity ischaemia and who were provided with rehabilitation in our COVID-19 unit were reviewed. CONCLUSION Coagulation changes related to SARS-CoV-2 may complicate recovery from this devastating disease. The rehabilitation management of amputated patients for COVID-19 acute lower extremity ischaemia is based on a multilevel approach for clinical, functional, nutritional and neuropsychological needs. Based on this limited experience, a dedicated programme for this specific group of patients seems advantageous to warrant the best functional outcome and quality of life.
Allogeneic Stem Cell Transplantation in Relapsed/Refractory Multiple Myeloma Treatment: Is It Still Relevant?

Background: Despite offering an attractive option, the role of allogeneic stem cell transplantation (alloSCT) for treatment of multiple myeloma (MM) remains unclear. Methods: Recognizing the paucity of data in the Asian population, we retrospectively evaluated the outcomes of 24 patients (median age 52) undergoing alloSCT between April 2003 and November 2017. Results: The median time from diagnosis to alloSCT was 39.4 months. The majority of the patients (70.8%) underwent alloSCT followed by reduced intensity conditioning regimens after a median of five lines of therapy. Among 24 patients, 15 patients (62.5%) had a high-risk MM feature. The two-year relapse-free survival (RFS) and overall survival (OS) of the total patients were 29.2 ± 9.3% and 44.3 ± 10.3%, respectively. Patients who were treated with less chemotherapy lines (<5) before alloSCT had a prolonged RFS and OS. All patients (seven patients) who received a myeloablative conditioning regimen had high-risk features, but two out of seven patients showed long-term survival without lasting sequelae. Nine patients (37.5%) experienced non-relapse mortality (NRM) within one year after alloSCT (the one-year cumulative incidence of NRM was 38.3 ± 10.1%). Conclusion: AlloSCT can still be implemented as effective salvage option in the treatment of relapsed/refractory high-risk MM. The optimal timing of alloSCT remains to be determined.
Influence of plant, animal and mixed resources on development of the zoophytophagous plant bug Campylomma verbasci (Hemiptera: Miridae)

The mullein bug, Campylomma verbasci (Meyer-Dür) (Hemiptera: Miridae), exploits both plant and animal resources. The aim of this study was (1) to evaluate the quality of different plant, animal and mixed diets (i.e. plant material or prey from the overwintering host, the summer host or the laboratory rearing) for the development and survival of mullein bug, and (2) to evaluate if the suitability of the resource changes according to the nymphal instar of C. verbasci. Mullein bug nymphs were reared individually in Petri dishes containing different diets and observed daily until reaching adulthood or dying. The rearing diet (living potato aphids + potato leaf + Ephestia eggs + apple pollen) was a high-quality diet. The medium-quality diets were apple fruit + apple pollen, Ephestia eggs and Sitotroga eggs. The low-quality diets included mullein leaf, frozen aphids, living aphids + potato leaf and apple fruit + living aphids + potato leaf. Finally, the inappropriate diets (when no nymphs reached adulthood) were agar gel, apple fruit, apple pollen, apple leaf, potato leaf, frozen spider mites and frozen conspecifics. When comparing the value of the diets for different instars, living aphids + potato leaf was a high-quality diet for third instar. Apple pollen and frozen conspecifics were low-quality diets for third instar. ‘Red Delicious’ fruit was a high-quality diet for fifth instar and low-quality for third instar. ‘Honeycrisp’ fruit constituted an inappropriate diet whatever the instar. Thus, a whole mixed diet maximises development and survival of C. verbasci nymphs.
Patency Rates After Successful Arteriovenous Fistula Thrombectomy: Relevance of the Flow/d-Dimer Ratio in the Decision-Making

Objectives: Surgical thrombectomy for acute arteriovenous fistula (AVF) thrombosis is one of the primary salvage intervention. The independent risk factors affecting the patency of AVF after a successful thrombectomy are yet unknown. Here, the author aimed to report the results of surgically corrected AVFs and the independent risk factors which may cause early failure following the surgical salvage. Methods: The study cohort comprised 24 patients who had acute AVF thrombosis and underwent successful surgical thrombectomy in the first 24 to 48 hours between January 2016 and April 2020 in our center. The study group was divided into patients with recurrent AVF thrombosis (n = 11, 45.8%) and without recurrent AVF thrombosis (n = 13, 54.1%) following surgical thrombectomy with a follow-up of 22.4 ± 6.8 months. Postthrombectomy primary and secondary patency of AVF were also evaluated. Results: The mean age of the cohort was 58.1 ± 15.2 years. A simple thrombectomy was performed for all cases. Only 2 cases have required a revision at the anastomosis due to severe intimal hyperplasia. Postthrombectomy primary patency rate was 45.5% for 18 months. Receiver operating characteristic analysis was performed with a resulting area under the curve value of 0.81 (95% CI: 0.35-0.94, P = .006) for flow (mL)/d-dimer (ng/mL) <0.63 in predicting recurrent AVF thrombosis following surgical thrombectomy. Conclusions: Flow (mL)/d-dimer (ng/mL) <0.63 was independent predictor of recurrent thrombosis (RT) of a surgically salvaged AVF. The patients at risk for RT or who may benefit from further intervention should be identified with predictive parameters.
Information Needs of Breast Cancer Patients: Theory-Generating Meta-Synthesis

Background Breast cancer has become one of the most frequently diagnosed carcinomas and the leading cause of cancer deaths. The substantial growth in the number of breast cancer patients has put great pressure on health services. Meanwhile, the information patients need has increased and become more complicated. Therefore, a comprehensive and in-depth understanding of their information needs is urgently needed to improve the quality of health care. However, previous studies related to the information needs of breast cancer patients have focused on different perspectives and have only contributed to individual results. A systematic review and synthesis of breast cancer patients’ information needs is critical. Objective This paper aims to systematically identify, evaluate, and synthesize existing primary qualitative research on the information needs of breast cancer patients. Methods Web of Science, EBSCO, Scopus, ProQuest, PubMed, PsycINFO, The Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature were searched on February 12 and July 9, 2019, to collect relevant studies. A Google Scholar search, interpersonal network recommendations, and reference chaining were also conducted. Eligible studies included qualitative or mixed-methods studies focusing on the information needs (across the cancer continuum) of breast cancer patients or their social networks. Subsequently, a Critical Appraisals Skills Programme checklist was used to assess the quality of included research. The results, findings, and discussions were extracted. Data analysis was guided by the theory-generating meta-synthesis and grounded theory approach. Results Three themes, 19 categories, and 55 concepts emerged: (1) incentives (physical abnormality, inquiry from others, subjective norm, and problems during appointments); (2) types of information needs (prevention, etiology, diagnosis, clinical manifestation, treatment, prognosis, impact and resumption of normal life, scientific research, and social assistance); (3) moderating variables (attitudes, health literacy, demographic characteristics, disease status, as well as political and cultural environment). The studies revealed that the information needs of breast cancer patients were triggered by different incentives. Subsequently, the patients sought a variety of information among different stages of the cancer journey. Five types of variables were also found to moderate the formation of information needs. Conclusions This study contributes to a thorough model of information needs among breast cancer patients and provides practical suggestions for health and information professionals.
Relationship Between serum SARS-CoV-2 nucleic acid(RNAemia) and Organ Damage in COVID-19 Patients: A Cohort Study

Abstract Background SARS-CoV-2 has spread worldwide and has the ability to damage multiple organs. However, information on serum SARS-CoV-2 nucleic acid(RNAemia) in patients affected by COVID-19 is limited. Methods Patients who admitted to Zhongnan Hospital of Wuhan University with laboratory-confirmed COVID-19, were tested SARS-COV-2 RNA in serum from January 28, 2020, to February 9, 2020. Demographic data, laboratory findings, radiological, comorbidities and outcomes data were collected and analyzed. Results 85 patients were included in the analysis. The viral load of throat swabs was significantly higher than serum samples. The highest detection of SARS-CoV-2 RNA in serum samples was between 11 to 15 days after the symptom onset. Analysis to compare with and without RNAemia provided evidence that CT and some laboratory biomarkers(total protein, BUN, LDH, hypersensitive troponin I and D-dimer) were abnormal, and that the extent of these abnormalities was generally higher in RNAemia than in non-RNAemia. Organ damages(respiratory failure, cardiac damage, renal damage and coagulopathy) were more common in RNAemia than non-RNAemia. Patients with vs without RNAemia had shorter durations from serum testing SARS-CoV-2 RNA. The mortality rate was higher among patients with vs without RNAemia. Conclusions This study provides evidence to support that SARS-CoV-2 may have an important role in multiple organ damage, such as respiratory failure, cardiac damage, renal damage and coagulopathy. We did not find strong evidence that SARS-CoV-2 plays a role in damage of liver and the central nervous system. And our evidence suggests that RNAemia has a significant association with a higher risk of in-hospital mortality.
Molecular Characterization of Porcine Epidemic Diarrhea Virus and Its New Genetic Classification Based on the Nucleocapsid Gene

Porcine epidemic diarrhea virus (PEDV) causes continuous, significant damage to the swine industry worldwide. By RT-PCR-based methods, this study demonstrated the ongoing presence of PEDV in pigs of all ages in Korea at the average detection rate of 9.92%. By the application of Bayesian phylogenetic analysis, it was found that the nucleocapsid (N) gene of PEDV could evolve at similar rates to the spike (S) gene at the order of 10−4 substitutions/site/year. Based on branching patterns of PEDV strains, three main N gene-base genogroups (N1, N2, and N3) and two sub-genogroups (N3a, N3b) were proposed in this study. By analyzing the antigenic index, possible antigenic differences also emerged in both the spike and nucleocapsid proteins between the three genogroups. The antigenic indexes of genogroup N3 strains were significantly lower compared with those of genogroups N1 and N2 strains in the B-cell epitope of the nucleocapsid protein. Similarly, significantly lower antigenic indexes in some parts of the B-cell epitope sequences of the spike protein (COE, S1D, and 2C10) were also identified. PEDV mutants derived from genetic mutations of the S and N genes may cause severe damage to swine farms by evading established host immunities.
Precision Medicine: Role of Biomarkers in Early Prediction and Diagnosis of Alzheimer’s Disease

Alzheimer’s disease (AD), the most common form of dementia in the aged people, is a chronic and irreversible neurodegenerative disorder. Early prediction, intervention, and objective diagnosis are very critical in AD. In this chapter, we will introduce the current progress in the prediction and diagnosis of AD, including recent development in diagnostic criteria, genetic testing, neuroimaging techniques, and neurochemical assays. Focus will be on some new applied methods with more specific examples, that is, cerebrospinal fluid (CSF) and blood proteins and peptides, which might serve as biomarkers for the diagnosis of AD. We will also discuss biomarker-based diagnostic strategies and their practical application. in AD pathogenesis. This may also be used in the clinical evaluation of patients. The results indicate that this strategy is advantageous for detecting low abundance proteins, especially from CNS, or various A β peptides as a biomarker of AD.
Perspective-taking is spontaneous but not automatic

Data from a range of different experimental paradigms—in particular (but not only) the dot perspective task—have been interpreted as evidence that humans automatically track the perspective of other individuals. Results from other studies, however, have cast doubt on this interpretation, and some researchers have suggested that phenomena that seem like perspective-taking might instead be the products of simpler behavioural rules. The issue remains unsettled in significant part because different schools of thought, with different theoretical perspectives, implement the experimental tasks in subtly different ways, making direct comparisons difficult. Here, we explore the possibility that subtle differences in experimental method explain otherwise irreconcilable findings in the literature. Across five experiments we show that the classic result in the dot perspective task is not automatic (it is not purely stimulus-driven), but nor is it exclusively the product of simple behavioural rules that do not involve mentalising. Instead, participants do compute the perspectives of other individuals rapidly, unconsciously, and involuntarily, but only when attentional systems prompt them to do so (just as, for instance, the visual system puts external objects into focus only as and when required). This finding prompts us to clearly distinguish spontaneity from automaticity. Spontaneous perspective-taking may be a computationally efficient means of navigating the social world.
Haematological and biochemical profile of weaner rabbits fed raw or processed pigeon pea seed meal based diets

Twenty four weaner rabbits of 6 - 8 weeks of age and averaging 550 g in weight were divided into four groups of six (6) rabbits per group and used in a 60 - day feeding trial for blood chemistry and haematological studies. The rabbits were fed raw or processed pigeon pea seed based diets in a Completely Randomized Design. Diet A contained raw (control), Diet B boiled, Diet C toasted and Diet D soaked pigeon pea seed meal (PSM) incorporated at 20% level in weaner rations. The haematological parameters investigated were haemoglobin (Hb), packed cell volume (PCV), white blood cell (WBC), neutrophil (N), lymphocyte (L) and eosinophil (E), while the biochemical components were urea, serum creatinine, bilirubin (total and conjugated), total protein, globulin, serum glutamic transaminase (SGPT) and serum glutamic oxalo acetic transaminase (SGOT). Results showed that white blood cells, lymphocytes, globulin and PCV values were influenced (P 0.05) for all groups. Not affected (P>0.05) by diets were blood urea, creatinine, bilirubin, total protein, SGOT and SGPT concentrations. Most haematological and biochemical values obtained were out of normal range for rabbits. Raw or processed pigeon pea did not support remarkable changes in haematological and biochemical profile for weaner rabbits at 20% dietary level of inclusion. Key words: Haematological, biochemical, blood profile, weaner rabbit, pigeon pea.
How academic achievement spreads: The role of distinct social networks in academic performance diffusion

Behavior diffusion through social networks is a key social process. It may be guided by various factors such as network topology, type of propagated behavior, and the strength of network connections. In this paper, we claim that the type of social interactions is also an important ingredient of behavioral diffusion. We examine the spread of academic achievements of first-year undergraduate students through friendship and study assistance networks, applying stochastic actor-oriented modeling. We show that informal social connections transmit performance while instrumental connections do not. The results highlight the importance of friendship in educational environments and contribute to debates on the behavior spread in social networks.
Effect of a Structured Teaching Module Including Intensive Prophylactic Measures on Reducing the Incidence of Capecitabine-Induced Hand-Foot Syndrome: Results of a Prospective Randomized Phase III Study.

LESSONS LEARNED A structured teaching module including intensive prophylactic measures to alleviate HFS during capecitabine therapy is feasible but ineffective at protecting patients from HFS. Pharmacologic therapeutic interventions should be investigated for the management of this complication. BACKGROUND Capecitabine-induced hand-foot syndrome (HFS) has a detrimental effect on quality of life. The effect of a structured teaching module including intensive prophylactic measures was evaluated. METHODS This non-crossover phase III double-blinded clinical trial randomized patients in a 1:1 ratio to either a control group or to a group administered a structured teaching model including intensive prophylactic measures on HFS administered by a trained oncology nurse at regular intervals (case) versus standard information on HFS care administered by treating clinician (control). The primary endpoint was comparison of fraction of patients in both arms developing at least grade 2 HFS. RESULTS Between June 15, 2016 and April 4 2018, 280 patients (140 to case and 140 to control) were enrolled. The median number of capecitabine chemotherapy cycles was eight; 269 patients (96%) were evaluable for HFS, of whom 89 patients (33.08%) developed at least grade 2 HFS [grade 2 HFS - 73 patients (26.1%); grade 3 HFS - 16 patients (5.7%)]. There was no difference in at least grade 2 HFS between evaluable case and control arms of the study [control group - 45/135 (33.3%); case - 44/134 (32.8%); p = . 93]. CONCLUSION The use of a structured teaching module including intensive prophylactic measures was feasible, but this did not reduce the incidence and severity of capecitabine-induced HFS.
