Bardet Biedl syndrome (BBS) is a rare inherited syndromic condition characterized by renal and extra-renal disorders. Renal defect, at either structural or functional level, is one of the cardinal clinical features, and is a major cause of morbidity. However, the pathogenic mechanism underlying its dysfunction remains largely unknown, and to date only symptomatic treatment with no specific therapy is available for these patients. Elucidating aberrant cellular and/or systemic processes that impact kidney function is therefore a prerequisite to develop targeted innovative therapeutic strategies for the BBS patients...

The role of the auxins indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) and of the auxin-interacting phytohormone ethylene, on the ectopic formation of primary xylem (xylogenesis in planta) is still little known. In particular, auxin/ethylene-target tissue(s), modality of the xylary process (trans-differentiation vs. de novo formation), and the kind of ectopic elements formed (metaxylem vs. protoxylem) are currently unknown. It is also unclear whether IBA may act on the process independently of conversion into IAA...

High-intensity exercise increases the concentration of circulating lactate. Cortical uptake of blood borne lactate increases during and following exercise, however the potential relationship with changes in the concentration of neurometabolites remains unclear. While changes in neurometabolite concentration have previously been demonstrated in primary visual cortex following exercise, it remains unknown whether these changes extend to regions such as sensorimotor cortex (SM) or executive regions such as dorsolateral prefrontal cortex (DLPFC)...

Treatment of patients with neck lymph node metastasis of squamous cell carcinoma (SCC) from unknown primary tumor (NSCCUP) is challenging due to the risk of missing occult tumors or inducing toxicity to unaffected sites. Human papillomavirus (HPV) is a promising biomarker given its causal link to oropharyngeal SCC and superior survival of patients with HPV-driven oropharyngeal SCC and NSCCUP. Identification of HPV-driven NSCCUP could focus diagnostic work-up and treatment on the oropharynx. For the first time, we assessed HPV antibodies and their prognostic value in NSCCUP patients...

Primary Cytomegalovirus (CMV) infection is often not suspected as a cause of fever of unknown origin (FUO) in immune-competent adults. We present a case-series of symptomatic primary CMV infection in immunocompetent adults presenting as fever of unknown origin (FUO). All patients with CMV serology tested between November 2008 and June 2016 underwent chart review. Cases were defined as those between 18 and 65 years of age with documented fever and elevated serum anti-CMV IgM. Exclusion criteria were organ specific CMV disease, positive serum anti-EBV IgM, or presence of any immunocompromising condition...

Functional neuroimaging studies argue that sensory deficits in hemiplegic cerebral palsy (HCP) are related to deviant somatosensory processing in the ipsilesional primary somatosensory cortex (S1). A separate body of structural neuroimaging literature argues that these deficits are due to structural damage of the ascending sensory tracts (AST). The relationship between the functional and structural integrity of the somatosensory system and the sensory performance is largely unknown in HCP. To address this relationship, we combined findings from magnetoencephalography (MEG) and probabilistic diffusion tractography (PDT) in 10 children with HCP and 13 typically developing (TD) children...

Background: The incidence of human papillomavirus- (HPV-) related oropharyngeal squamous cell carcinoma (OPSCC) has been rapidly increasing worldwide. HPV is reported in approximately 50% cases of OPSCC in Japan. However, there are few reports of synchronous bilateral HPV-positive tonsillar carcinoma, and, in almost all those cases, carcinoma was detected using positron emission tomography/computed tomography and/or bilateral tonsillectomy. Methods and Results: We report the case of a 63-year-old male with bilateral tonsillar carcinoma detected using transoral endoscopic examination with narrow-band imaging (NBI)...

Papillary thyroid carcinoma (PTC) is the most common malignant neoplasm of the thyroid. Majority of the PTC carries an excellent prognosis. However, patients with tall cell variant (TCV) of papillary thyroid carcinoma have a worse prognosis than those with the classic variant. On the other hand, squamous cell carcinoma of the thyroid (SCT) is an unusual neoplasm thought to arise as a primary tumor or as a component of an anaplastic or undifferentiated carcinoma. We report a patient with TCV of PTC presenting years later with squamous transformation...

NF-κB is a transcription factor involved in the regulation of multiple physiological and pathological cellular processes, including inflammation, cell survival, proliferation, and cancer cell metastasis. NF-κB is frequently hyperactivated in several cancers, including triple-negative breast cancer. Here we show that NF-κB activation in breast cancer cells depends on the presence of the CHORDC1 gene product Morgana, a previously unknown component of the IKK complex and essential for IκBα substrate recognition...

Docosahexaenoic acid (DHA) has been suggested to inhibit adipogenesis in fish; the mechanism behind this observation remains largely unknown. The present study was to investigate the effects of DHA on the adipocyte differentiation of grass carp by using transcriptomic technology. Confluent primary cultured differentiating adipocytes were co-incubated with either 0μM or 100μM DHA for 2days (early phase of differentiation) and 7days (late phase). The results showed that 100μM DHA promoted adipogenesis at 2days but decreased lipid accumulation at 7days of treatment compared to that of the control...
