The signaling network formed by external environmental signals and endogenous hormone signals is an important basis for the adaptive growth of plants. We recently identified a UDP-glucosyltransferase gene, UGT76F1, which controls the glucosylation of auxin precursor IPyA and mediates light-temperature signaling to regulate auxin-dependent hypocotyl elongation in Arabidopsis. However, it is unclear whether UGT76F1 is involved in the adaptive growth of other tissues and whether it is related to the signaling of other hormones besides auxin. Here we investigated the petiole elongation of UGT76F1 overexpression lines and knockout mutant lines, and also studied the effects of UGT76F1 on BR signaling. Experimental results indicated that UGT76F1 is involved in the PIF4-mediated petiole growth under high temperature and that UGT76F1 is also related to the BR signaling in controlling hypocotyl growth. These results suggest that UGT76F1 may have a wider significance in the plant adaptations to surrounding environments.T2D is a complex disease with poorly understood mechanisms. In Asian Indians, it is associated with "thin fat" phenotype which resembles with partial lipodystrophy. We hypothesized that disturbed expression of lipodystrophy genes might play a role in T2D pathogenesis. Therefore, we attempted to establish a link between these two diseases by studying the overlap between the network of lipodystrophy genes and the differentially expressed genes (DEGs) in the peripheral subcutaneous adipose tissue of Asian Indians diabetics. We found that 16, out of 138 lipodystrophy genes were differentially regulated in diabetics and around 18% overlap between their network and the DEGs; the expression level of lipodystrophy genes showed an association with disease-related intermediate phenotypic traits among diabetics but not in the control group. We also attempted to individualize the diabetic patients based on ±2 fold altered expression of lipodystrophy genes as compared to their average expression in the control group. In conclusion, significant overlap exists between some of the lipodystrophy genes and their network with DEGs in the peripheral adipose tissue in diabetics. They possibly play a role in the pathogenesis of diabetes and individualization of diabetics is possible based on their altered expression in their peripheral adipose tissue.Objective To compare the effect of a rapid low-level laser therapy (LLLT) protocol to Michigan occlusal splint in the treatment of myofascial pain, as well as to evaluate their impact on Oral Health-Related Quality of Life (OHRQoL). Methods Thirty participants were randomly allocated into three groups G1 occlusal splint (n = 11), G2 LLLT (n = 10), and G3 LLLT placebo (n = 9). LLLT and placebo were applied in the points of pain upon palpation. Results G1 presented improvement in pain (p = 0.014) and in the diagnosis of myofascial pain (p = 0.008), while G2 and G3 did not. Regarding OHRQoL, G1 and G2 presented significant improvement (p = 0.005, in both), whereas, G3 did not. Conclusion Michigan occlusal splint was effective in reducing pain and improving OHRQoL. Treatment with the rapid LLLT protocol only provided an improvement in OHRQoL.The risk of developing severe illness from COVID-19 and of dying from it increases with age. This statistical association has led to numerous highly problematic policy suggestions and comments revealing underlying ageist attitudes and promoting age discrimination. Such attitudes are based on negative stereotypes on the health and functioning of older adults. As a result, the lives of older people are disvalued, including in possible triage situations and in the potential limitation of some measures against the spread of the pandemic to older adults. These outcomes are unjustified and unethical. We develop six propositions against the ageism underlying these suggestions to spur a more adequate response to the current pandemic in which the needs and dignity of older people are respected.Purpose Immune checkpoint inhibitors (ICIs) are standard therapy in metastatic renal cell carcinoma (RCC). The safety and activity of the combination of ipilimumab and nivolumab in patients who have received prior ICI targeting the programmed death 1 (PD-1) pathway remains unknown. We evaluated ipilimumab and nivolumab in patients with metastatic RCC after prior treatment with anti-PD-1 pathway-targeted therapy. Patients and methods Patients with metastatic RCC who received prior anti-PD-1 pathway-targeted therapy and subsequently received ipilimumab and nivolumab were reviewed. Objective response rate and progression-free survival per investigator assessment were recorded. Toxicity of ipilimumab and nivolumab was also assessed. Results Forty-five patients with metastatic RCC were included. All patients (100%) received prior ICIs targeting the PD-1 pathway. The median age was 62 years (range, 21-82 years). At a median follow-up of 12 months, the objective response rate to ipilimumab and nivolumab was 20%. The median progression-free survival while on ipilimumab and nivolumab was 4 months (range, 0.8-19 months). Immune-related adverse events (irAEs) of any grade with ipilimumab and nivolumab were recorded in 29 (64%) of the 45 patients; grade 3 irAEs were recorded in 6 (13%) of the 45 patients. Conclusion Ipilimumab and nivolumab demonstrated antitumor activity with acceptable toxicity in patients with metastatic RCC who had prior treatment with checkpoint inhibition.Scene processing is fundamentally influenced and constrained by spatial layout and spatial associations with objects. However, semantic information has played a vital role in propelling our understanding of real-world scene perception forward. In this article, we review recent advances in assessing how spatial layout and spatial relations influence scene processing. We examine the organization of the larger environment and how we take full advantage of spatial configurations independently of semantic information. We demonstrate that a clear differentiation of spatial from semantic information is necessary to advance research in the field of scene processing.

These intrinsically photosensitive retinal ganglion cells (ipRGCs) have well-established roles in a variety of reflex responses to changes in ambient light intensity, including circadian photoentrainment. In this article, we review the growing evidence, obtained primarily from laboratory mice and humans, that the ability to sense light via melanopsin is also an important component of perceptual and form vision. Melanopsin photoreception has low temporal resolution, making it fundamentally biased toward detecting changes in ambient light and coarse patterns rather than fine details. Nevertheless, melanopsin can indirectly impact high-acuity vision by driving aspects of light adaptation ranging from pupil constriction to changes in visual circuit performance. Melanopsin also contributes directly to perceptions of brightness, and recent data suggest that this influences the appearance not only of overall scene brightness, but also of low-frequency patterns.

CMV infections are frequently symptomatic in case of a primary infection during pregnancy. Generally, maternal immunity protects the newborn against a symptomatic course of the CMV infection. Methods We present clinical information and medical images of a neonate with non-primary congenital CMV infection. Results We report the case of a severe congenital infection in a newborn clinically presenting with diffuse petechia, facial dysmorphisms, respiratory distress, hepatomegaly and hypotonia. The girl was born to a mother with CMV immunity. Blood results demonstrated thrombocytopenia and elevated transaminases. Brain MRI revealed ventricular dilatation and germinolytic cysts, compatible with CMV infection. Auditory brain stem response testing was abnormal. CMV culture of saliva was positive. This led to the diagnosis of a severe congenital CMV infection due to a non-primary maternal infection. Antiviral treatment with valganciclovir was initiated immediately and continued for 6 months. Conclusion Our case illustrates that, even when the mother was demonstrated CMV immune, congenital CMV infection is still an important differential diagnostic consideration in neonates presenting with congenital cerebral abnormalities, thrombocytopenia and/or hearing loss.

Even with surgical intervene, complete remission of this disease is not approachable. Therefore, understanding the factors relevant to disease severity and prognosis will do help to the treatment strategy and health management of this disease.Objective This study aimed to explore the clinic, laboratory and socioeconomic characteristics of patients and evaluate the risk factors for aggressive JORRP.Methods The information of clinical and socioeconomic status of the patients was reviewed and its association with disease severity was analyzed. Papilloma from JORRP patients undergone surgeries was used to determine HPV subtypes by real-time PCR. The profiles of mRNA expression in the papilloma were assessed using microarray.Results Age at diagnosis and socioeconomic status were shown to associate with the severity of JORRP. There was no differential severity considering different HPV subtype. The mRNA expression of nucleotide binding oligomerization domain receptor protein 3 (NLRP3) and Gasdermin B (GSDMB) was reduced in papillomas.Conclusions A younger age at diagnosis and low socioeconomic status were associated with the severity of JORRP. mRNA expression of NLRP3 and GSDMB in the papillomas of JORRP patients was significantly reduced.Abbreviation JORRP Juvenile-onset recurrent respiratory papillomatosis; RRP Recurrent respiratory papillomatosis; OSAS Obstructive sleep apnea syndrome; NLRP3 Nucleotide binding oligomerization domain receptor protein 3; GSDMB Gasdermin B.Actomyosin cortical contractility drives many cell shape changes including cytokinetic furrowing. INCB059872 While positive regulation of contractility is well characterized, counterbalancing negative regulation and mechanical brakes are less well understood. The small GTPase RhoA is a central regulator, activating cortical actomyosin contractility during cytokinesis and other events. Here we report how two novel cytokinetic ring components, GCK-1 and CCM-3, participate in a negative feedback loop among RhoA and its cytoskeletal effectors to inhibit contractility. GCK-1 and CCM-3 are recruited by active RhoA and anillin to the cytokinetic ring, where they in turn limit RhoA activity and contractility. This is evidenced by increased RhoA activity, anillin and non-muscle myosin II in the cytokinetic ring, and faster cytokinetic furrowing, following depletion of GCK-1 or CCM-3. GCK-1 or CCM-3 depletion also reduced RGA-3 levels in pulses, and increased baseline RhoA activity and pulsed contractility during zygote polarization.
