    Abstract A novel hybrid visible-light photodetector was created using a planar p-type inorganic NiO layer in a junction with an organic electron acceptor layer. The effect of different oxygen pressures on formation of the NiO layer by pulsed laser deposition shows that higher pressure increases the charge carrier density of the film and lowers the dark current in the device. The addition of a monolayer of small molecules containing conjugated π systems and carboxyl groups at the device interface was also investigated and with correct alignment of the energy levels improves the device performance with respect to the quantum efficiency, responsivity, and photogeneration. The thickness of the organic layer was also optimized for the device, giving a responsivity of 1.54 × 10(-2) A W(-1) in 460 nm light.

    Abstract Cu(2)O nanoneedles are synthesized on a copper substrate by a simple anodization and reducing ambient annealing protocol. ZnO nanorods are grown on ITO coated glass by a low temperature chemical route. The electronic and photo-response properties of the p-Cu(2)O/n-ZnO flip-chip heterojunction are then studied and analyzed. We show that the I-V characteristic is rectifying and the junction exhibits a good photoresponse (∼120% under 1 V reverse bias) under AM 1.5 (1 Sun) illumination. This nano-heterojunction photo-response is far stronger as compared to that of a pulsed laser deposited thin film p-Cu(2)O/n-ZnO heterojunction, which can be attributed to higher junction area in the former case.

    Abstract Idiopathic generalized epilepsies (IGEs) are a group of epilepsies characterized by an underlying genetic predisposition and a good response to antiseizure medicines (ASMs) in the majority of the patients. Of the various broad-spectrum ASMs, valproate is the most effective medicine for the control of seizures in IGEs. However, with the availability of many newer ASMs and evidence showing the high teratogenic potential of valproate, the choice of ASMs for IGEs has become increasingly difficult, especially in women of the child-bearing age group. In this article, we review the current evidence regarding the efficacy and safety of various ASMs in patients with IGEs and provide practical guidelines for choosing appropriate ASMs in various subgroups of patients with IGEs.

    Abstract Background and purpose: According to WHO statistics, approximately 6.9 billion people worldwide had been vaccinated against SARS-CoV-2 as at October 27, 2021, including around 1.0 billion people in India. Most Indian recipients received the Covishield (ChAdOx1-S/nCoV-19) vaccine, followed by the Covaxin (an inactivated SARS-CoV-2 antigen) vaccine. This study was conducted to characterize the neurological phenotypic spectrum of patients with adverse events following immunization with any of the available COVID-19 vaccines in India (Covishield or Covaxin) during the study period and their temporal relationship with vaccination.
    Methods: This ambispective multicenter hospital-based cohort study covered the period from March to October 2021. The study included all cases suspected of having neurological complications following COVID-19 vaccination.
    Results: We report a spectrum of serious postvaccination neurological complications comprising primary central nervous system demyelination (4 cases), cerebral venous thrombosis (3 cases), Guillain-Barre syndrome (2 cases), vaccine-induced prothrombotic immune thrombocytopenia syndrome (2 cases), cranial nerve palsies (2 cases), primary cerebral hemorrhage (1 case), vestibular neuronitis (1 case), chronic inflammatory demyelinating polyneuropathy (1 case), generalized myasthenia (1 case), and seizures (1 case).
    Conclusions: Although the benefits of vaccination far outweigh its risks, clinicians must be aware of possible serious adverse events associated with COVID-19 vaccinations.

    Abstract Neurotuberculosis is one of the commonest HIV-associated opportunistic infections (OI) of the CNS. Cross-talk between HIV, Mycobacterium tuberculosis and host immune responses may alter expression of pattern recognition receptors (PRRs), thereby affecting cytokine profiles and functional responses. We examined PRR mRNA expression and cytokine and granzyme levels in HIV infected individuals with neurotuberculosis and found significant downregulation of TLR9 and increased MDA5 expression compared to healthy subjects. Significantly higher Granzyme A and IFN-γ levels were also observed in the CSF of this group compared to CSF from non-infectious controls. These alterations may lead to inappropriate recruitment of immune cells to the CNS, leading to disease severity.
