Neuronal dynamics of cerebellum and medial prefrontal cortex in adaptive motor timing.

Precise temporal control of sensorimotor coordination and adaptation is a fundamental basis of animal behavior. How different brain regions are involved in regulating the flexible temporal adaptation remains elusive. Here, we investigated the neuronal dynamics of the cerebellar interposed nucleus (IpN) and the medial prefrontal cortex (mPFC) neurons during temporal adaptation between delay eyeblink conditioning (DEC) and trace eyeblink conditioning (TEC).

Alopecia areata exhibits cutaneous and systemic OX40 activation across atopic backgrounds.

Background: Alopecia areata (AA) is a chronic, nonscarring hair-loss disorder associated with significant quality-of-life impairment and limited treatment options. AA has been recently linked to atopy and shown to exhibit both Th1- and Th2-driven inflammation. However, a comprehensive molecular and cellular characterization across blood and scalp compartments in both atopic and nonatopic patients is lacking.

A Rare Case of Thyroidea Ima Arising From the Internal Thoracic Artery and Reaching Up to the Parathyroid Gland.

The thyroidea ima artery (TIA), also known as the Neubauer artery, is a variable artery that takes part in the blood supply of the thyroid gland. The overall prevalence rate of the thyroidea ima artery is 3.3%.

Blood parameters of adult marsh frogs Pelophylax ridibundus (Amphibia: Ranidae) in rice paddies subjected to intense agrochemical use.

We present the results of an in situ study of a set of blood parameters in adult marsh frogs (Pelophylax ridibundus (Pallas 1771) from populations inhabiting the largest system of rice fields in Bulgaria, the Tsalapitsa rice fields (TRF), under chronic stress conditions.

Sclerotic-Type Cutaneous Chronic Graft-Versus-Host Disease Exhibits Activation of T Helper 1 and OX40 Cytokines.

Sclerotic-type cutaneous chronic graft-versus-host disease is a severe complication of allogeneic hematopoietic stem cell transplantation, with profound morbidity. A dearth of effective, targeted treatment options necessitates further investigation into the molecular mechanisms underlying this T-cell-mediated disease. In this study, we compared the transcriptome in skin biopsies from pediatric and young adult (aged <25 years) patients with sclerotic-type cutaneous chronic graft-versus-host disease (n = 7) with that in demographically matched healthy controls (n = 8) and patients with atopic dermatitis (n = 10) using RNA sequencing with RT-PCR and immunohistochemistry validation.

Excitatory nucleo-olivary pathway shapes cerebellar outputs for motor control.

The brain generates predictive motor commands to control the spatiotemporal precision of high-velocity movements. Yet, how the brain organizes automated internal feedback to coordinate the kinematics of such fast movements is unclear. Here we unveil a unique nucleo-olivary loop in the cerebellum and its involvement in coordinating high-velocity movements.

Scalp biomarkers during dupilumab treatment support Th2 pathway pathogenicity in alopecia areata.

Background: The mechanisms driving alopecia areata (AA) are still unclear, hindering development of targeted therapeutics. Specific Th2 targeting with dupilumab in AA provides a unique opportunity to dissect its pathogenesis and explore the role of Th2 pathway.

Methods: We evaluated changes in scalp biomarkers in AA patients (with and without concomitant atopy) randomized to weekly dupilumab or placebo for 24 weeks, followed by open-label dupilumab for 24 weeks.

Does dihydropyrimidine dehydrogenase level modify plasma antioxidant capacity in colorectal cancer patients treated with fluoropyrimidines?

Introduction: Colorectal cancer is the third most common cancer type worldwide. Fluoropyrimidines and their prodrug-based regimens are widely applied as primary medications. The main enzyme responsible for the rate-limiting step in pyrimidine and for the 5-fluorouracil catabolism is dihydropyrimidine dehydrogenase (DPD).

First report of Cucurbit aphid-borne yellows virus causing yellowing disease on pumpkin (Cucurbita pepo) and cucumber (Cucumis sativus) in Bulgaria.

Cucurbit aphid-borne yellows virus (CABYV) was first reported in France in 1992 but has since been observed worldwide (Lecoq et al. 1992; Choi and Choi 2016; Buzkan et al. 2017; Zindovic et al.

Scalp and serum profiling of frontal fibrosing alopecia reveals scalp immune and fibrosis dysregulation with no systemic involvement.

Background: Frontal fibrosing alopecia (FFA) is a progressive, scarring alopecia of the frontotemporal scalp that poses a substantial burden on quality of life. Large-scale global profiling of FFA is lacking, preventing the development of effective therapeutics.

Objective: To characterize FFA compared to normal and alopecia areata using broad molecular profiling and to identify biomarkers linked to disease severity.

An -Derived Biostimulant Protects Model and Crop Plants from Oxidative Stress.

Abiotic stresses, which at the molecular level leads to oxidative damage, are major determinants of crop yield loss worldwide. Therefore, considerable efforts are directed towards developing strategies for their limitation and mitigation. Here the superoxide-inducing agent paraquat (PQ) was used to induce oxidative stress in the model species and the crops tomato and pepper.

QTL mapping for benzoxazinoid content, preharvest sprouting, α-amylase activity, and leaf rust resistance in rye (Secale cereale L.).

Mapping population of recombinant inbred lines (RILs) representing 541 × Ot1-3 cross exhibited wide variations of benzoxazinoid (BX) content in leaves and roots, brown rust resistance, α-amylase activity in the grain, and resistance to preharvest sprouting. QTL mapping of major BX species using a DArT-based map revealed a complex genetic architecture underlying the production of these main secondary metabolites engaged in stress and allelopathy responses. The synthesis of BX in leaves and roots was found to be regulated by different QTL.

An integration of photosynthetic traits and mechanisms that can increase crop photosynthesis and grain production.

The hypothesis we propose is that during photosynthesis the balance between potentially detrimental and beneficial photochemically induced events can be tipped beneficially toward increased photosynthesis and toward increased crop yield. To test this hypothesis a procedure has been devised with the rice plant, Oryza sativa, that has resulted in increasing both canopy photosynthesis and rice grain yield. Two elite rice varieties selected independently in the contrasting environments of either South China or Texas, each with distinct photosynthetic traits, were crossed to produce a hybrid with an increased canopy photosynthesis and grain yield that is regularly 20 to 22% higher than the mid-yields of the parents.

Novel characteristics of cassava, Manihot esculenta Crantz, a reputed C3-C 4 intermediate photosynthesis species.

The cassava plant, Manihot esculenta, grows exceptionally well in low fertility and drought prone environments, but the mechanisms that allow this growth are unknown. Earlier, and sometimes contradictory, work speculated about the presence of a C4-type photosynthesis in cassava leaves. In the present work we found no evidence for a C4 metabolism in mature attached cassava leaves as indicated i) by the low, 2 to 8%, incorporation of (14)CO2 into C4 organic acids in short time periods, 10 s, and the lack of (14)C transfer from C4 acids to other compounds in (12)CO2, ii) by the lack of C4 enzyme activity changes during leaf development and the inability to detect C4 acid decarboxylases, and iii) by leaf CO2 compensation values between 49 and 65 μl of CO2 1(-1) and by other infrared gas exchange photosynthetic measurements.
