The Cotton High-affinity K+ Transporter, GhHAK5a, is Essential for Shoot Regulation of K+ Uptake in Root under Potassium Deficiency.

Potassium (K) deficiency is a key limiting factor in cotton (Gossypium hirsutum) production. By grafting two contrasting cotton cultivars, CCRI41 (more susceptible to K+ deficiency) and SCRC22 (more tolerant of K+ deficiency), we established that cotton shoot plays a vital role in the regulation of root K+ uptake. To identify the genetic basis of this finding, we performed RNA sequencing (RNA-seq)...

Pelvic incidence as a prognostic factor in coccydynia.

Although obesity, and trauma have been found as independent prognostic factors in coccydynia, the only radiological prognostic factor is posterior shift of the coccyx. The aim of this study is to evaluate the pelvic incidence (PI) of coccydynia patients treated by different methods and to determine whether it is a risk factor or a prognostic factor.

The Predictive Value of Insulin-Like Growth Factor 1 in Irradiation-Dependent Growth Hormone Deficiency in Childhood Cancer Survivors.

The literature contains conflicting reports on the value of low insulin-like growth factor 1 (IGF-1) levels in predicting radiation-induced growth hormone (GH) deficiency (GHD) in childhood cancer survivors (CCS). These reports often involve small samples of patients who have received irradiation or mixed cohorts including non-irradiated subjects.

The clinical importance of BRCAness in a population-based cohort of Danish epithelial ovarian cancer.

Germline mutations in genes predict improved survival and sensitivity to treatment with poly(adenosine-diphosphate-ribose) polymerase inhibitors in epithelial ovarian carcinoma. The prognostic importance of other genetic alterations leading to homologous recombination deficiency, collectively BRCAness phenotype, is unresolved. The aim was to analyze the distribution of homologous recombination de...

Prognostic value of uPAR expression and angiogenesis in primary and metastatic melanoma.

Angiogenesis is important for the progression of cutaneous melanoma. Here, we analyzed the prognostic impact of the angiogenic factor urokinase plasminogen activator resecptor (uPAR), vascular proliferation index (VPI) and tumor necrosis as a measure of hypoxia in a patient series of nodular melanomas (n = 255) and matched loco-regional metastases (n = 78). Expression of uPAR was determined by imm...

Forearm lengthening and prosthetic management in children with transverse congenital forearm deficiency.

In cases of transverse congenital forearm deficiency, achieving a good prosthesis fit during childhood remains a challenge. Ulnar lengthening is a treatment option for improving the prosthesis fit. The objective of this study was to evaluate surgical ulnar lengthening and the subsequent prosthesis fit. We reviewed four cases of ulnar lengthening in children with transverse congenital forearm defic...

Hepatocyte Growth Factor-Secreting Mesothelial Cell Sheets Suppress Progressive Fibrosis in a Rat Model of CKD.

Although hepatocyte growth factor (HGF) has antifibrotic effects and is involved in angiogenesis and vasodilation, systemic administration of HGF to prevent kidney fibrosis is not a feasible strategy for suppressing interstitial fibrosis in patients with CKD.

Factor V Leiden.

Factor V Leiden thrombophilia is a genetic mutation that results in hypercoagulation of the blood that presents life-threatening symptoms. This article describes the role of imaging in diagnosis and treatment of cardiovascular complications caused by factor V Leiden and summarizes the etiology, risk factors, symptoms, diagnostic measures, progression, prognosis, and treatment of the mutation.

A Nervous System-Specific Model of Creatine Transporter Deficiency Recapitulates the Cognitive Endophenotype of the Disease: a Longitudinal Study.

Mutations in creatine (Cr) transporter (CrT) gene lead to cerebral creatine deficiency syndrome-1 (CTD), an orphan neurodevelopmental disorder presenting with brain Cr deficiency, intellectual disability, seizures, movement and autistic-like behavioral disturbances, language and speech impairment. We have recently generated a murine model of CTD obtained by ubiquitous deletion of 5-7 exons in the ...

Zinc Deficiency and Arsenic Exposure Can Act Both Independently or Cooperatively to Affect Zinc Status, Oxidative Stress, and Inflammatory Response.

The negative health impact of zinc deficiency overlaps significantly with arsenic exposure, and is associated with increased risk for chronic diseases. Arsenic contamination in the groundwater often co-exists in regions of the world that are prone to zinc deficiency. Notably, low zinc status shares many hallmarks of arsenic exposure, including increased oxidative stress and inflammation. Despite t...

ITGB4 deficiency induces senescence of airway epithelial cells through p53 activation.

Aging is characterized by a progressive loss of physiological integrity, leading to impaired organ function and, ultimately, increased vulnerability to death. Many complex diseases are related to aging, including asthma. In the lung, the airway epithelium serves as the first barrier to prevent the access of inspired external stimuli and dictates the initial stress responses. Notably, in the airway...

Broadening the Female Athlete Triad: Relative Energy Deficiency in Sport.

Frequency of occurrence of four- and five-factor WAIS-IV profiles.

Interpretive strategies for the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) include Wechsler's four-factor structure and the five-factor Cattell-Horn-Carroll (CHC) model. The frequency of profile occurrence and the contribution of demographic- and ability-related variables to their incidence are unknown. Current participants were 291 referrals (males = 134; female = 157) for neurops...

Risk factors associated with severe outcomes in adult hospitalized patients according to influenza type and subtype.

Seasonal influenza is a cause of hospitalization, especially in people with underlying disease or extreme age, and its severity may differ depending on the types and subtypes of circulating viruses. We investigated the factors associated with ICU admission or death in hospitalized patients with severe laboratory-confirmed influenza according to the viral type and subtype. An observational epidemio...

Dose tailoring of human cell line-derived recombinant factor VIII simoctocog alfa: using a limited sampling strategy in patients with severe haemophilia A.

The use of prophylaxis in haemophilia A is considered the standard of care, particularly in children. Despite adjustment of doses for body weight and/or age, a large pharmacokinetic (PK) variability between patients has been observed. PK-tailored prophylaxis may help clinicians adjust coagulation factor FVIII activity (FVIII:C) to...

RANK deletion in NPY neurons attenuates estrogen deficiency related bone loss.

The RANKL pathway is known to be an important aspect of the pathogenesis of estrogen-deficiency induced bone loss. RANK deletion specifically in NPY neurons has been shown to enhance the ability of the skeleton to match increases in body weight caused by high fat diet feeding, likely via the modulation of NPY levels. Here, we use ovariectomy in female mice to show that RANK deletion in NPY neurons...

Bayesian pharmacokinetic-guided prophylaxis with recombinant factor VIII in severe or moderate haemophilia A.

Personalised pharmacokinetics (PK) using Bayesian analysis with limited sampling is assumed to help to optimise prophylaxis in haemophilia A (HA) patients.

Combining individual Chlamydia trachomatis IgG antibodies MOMP, TARP, CPAF, OMP2, and HSP60 for tubal factor infertility prediction.

Tubal factor infertility (TFI) is a severe complication of genital C. trachomatis infections. In fertility work-up chlamydia antibody test (CAT) is used to predict TFI. The predictive value for TFI of most commonly used CAT is moderate.

Prevention of relapse in patients with acquired thrombotic thrombocytopenic purpura undergoing elective surgery: a case series.

Severe ADAMTS13 deficiency has been recognized as the main risk factor for recurrence of thrombotic thrombocytopenic purpura (TTP). Several conditions including surgery may influence the levels of ultra large Von Willebrand factor and ADAMTS13, acting as a trigger for an acute TTP event.
