The proposed sensor was successfully applied in HBV DNA detection in sera from patients without any amplification step (e.g., PCR) required, thus simplifying the operation further. Additionally, the results obtained from this present device are in accordance with the standard real-time PCR, thus supporting the accuracy of the method.Increasing evidence suggests that long non-coding RNAs (lncRNAs) are involved in neuroblastoma (NB) pathogenesis. The aim of this study was to elucidate the roles and underlying mechanism of non-coding RNA activated by DNA damage (NORAD) in childhood NB. Both public data and clinical specimens were used to determine NORAD expression. Colony formation, cell proliferation and wound healing assays were performed to evaluate NORAD effects on proliferation and migration of SH-SY5Y and SK-N-BE(2) cells. Flow cytometry was used to examine the cell cycle changes. The expression of genes and proteins involved in chromosomal instability was determined by qRT-PCR and western blotting, respectively. Our results showed that low NORAD expression correlated with advanced tumor stage, high risk and MYCN amplification in both public data and clinical samples. Kaplan-Meier analysis indicated that patients with low NORAD expression had poor survival outcomes. Functional research showed that NORAD knockdown promoted cell proliferation and migration, and arrested the cell cycle at the G2/M phase. Moreover, the expression of the DNA damage sensor, PARP1, increased after NORAD knockdown, indicating a potential contribution of NORAD to DNA damage repair. NORAD silencing also affected the expression of genes and proteins related to sister chromatid cohesion and segregation, which are involved in chromosomal instability and consequent aneuploidy. These results suggest that NORAD may serve as a tumor suppressor in NB pathogenesis and progression. Thus, NORAD is a potential therapeutic target and a promising prognostic marker for NB patients.
Obstructive sleep apnea (OSA) is characterized by repeated episodes of complete or partial obstruction of the upper airways, leading to chronic intermittent hypoxia (IH). OSA patients are considered at high cerebrovascular risk and may also present cognitive impairment. One hypothesis explored is that disturbances may be linked to blood-brain barrier (BBB) dysfunction. click here The BBB is a protective barrier separating the brain from blood flow. The BBB limits the paracellular pathway through tight and adherens junctions, and the transcellular passage by efflux pumps (ABC transporters). The aims of this study were to evaluate the impact of IH and sustained hypoxia (SH) on a validated in vitro BBB model and to investigate the factors expressed under both conditions.
Exposure of endothelial cells (HBEC-5i) in our in vitro model of BBB to hypoxia was performed using IH cycles 1% O2-35 min/18% O2-25 min for 6 cycles or 6 h of SH at 1% O2. After exposure, we studied the cytotoxicity and the level of ROS in our cells. essential in order to propose new therapeutic strategies for patients with OSA.
Chronic subdural hematoma is a common neurologic disorder that is especially prevalent among older people. The effect of dexamethasone on outcomes in patients with chronic subdural hematoma has not been well studied.
We conducted a multicenter, randomized trial in the United Kingdom that enrolled adult patients with symptomatic chronic subdural hematoma. The patients were assigned in a 11 ratio to receive a 2-week tapering course of oral dexamethasone, starting at 8 mg twice daily, or placebo. The decision to surgically evacuate the hematoma was made by the treating clinician. The primary outcome was a score of 0 to 3, representing a favorable outcome, on the modified Rankin scale at 6 months after randomization; scores range from 0 (no symptoms) to 6 (death).
From August 2015 through November 2019, a total of 748 patients were included in the trial after randomization - 375 were assigned to the dexamethasone group and 373 to the placebo group. The mean age of the patients was 74 years, and 94% underwen index admission, treatment with dexamethasone resulted in fewer favorable outcomes and more adverse events than placebo at 6 months, but fewer repeat operations were performed in the dexamethasone group.

Among adults with symptomatic chronic subdural hematoma, most of whom had undergone surgery to remove their hematomas during the index admission, treatment with dexamethasone resulted in fewer favorable outcomes and more adverse events than placebo at 6 months, but fewer repeat operations were performed in the dexamethasone group.

Asenapine is a second-generation antipsychotic used to treat individuals with schizophrenia. This phase 3 study assessed efficacy and safety of HP-3070, an asenapine transdermal system (patch), in adults with schizophrenia.
In this inpatient study, a 3- to 14-day screening/single-blind run-in washout period was followed by a 6-week double-blind period wherein patients with acutely exacerbated schizophrenia (DSM-5 criteria) were randomized 111 and received HP-3070 7.6 mg/24 h (n = 204), HP-3070 3.8 mg/24 h (n = 204), or placebo (n = 206). Primary endpoint was change from baseline (CFB) in week 6 Positive and Negative Syndrome Scale (PANSS) total score versus placebo; key secondary endpoint was CFB in week 6 Clinical Global Impression-Severity of Illness score versus placebo. Safety endpoints included treatment-emergent adverse events (TEAEs) and dermal assessments.
Each of the HP-3070 doses demonstrated significant improvement versus placebo at week 6 for the primary and key secondary endpoints. Differences in the least-squares mean (LSM) (95% CI; adjusted P) of CFB for PANSS total scores were -4.8 (-8.06 to -1.64; adjusted P = .003) and -6.6 (-9.81 to -3.40; adjusted P < .001) for 7.6 mg/24 h and 3.8 mg/24 h, respectively. HP-3070 was well tolerated, with a systemic safety profile consistent with sublingual asenapine. Incidence of application site TEAEs was higher for HP-3070 (14.2%, 7.6 mg/24 h; 15.2%, 3.8 mg/24 h) versus placebo (4.4%). Discontinuations due to application site reactions or skin disorders (urticaria, pruritus) were infrequent (≤ 0.5% per treatment group).
HP-3070 7.6 mg/24 h and 3.8 mg/24 h doses were efficacious and well tolerated. As the first transdermal antipsychotic patch available in the US, HP-3070 offers a novel treatment option for people with schizophrenia.
