Subcapsular liver haematoma in pregnancy, a rare and life-threatening condition, is more commonly associated with severe preeclampsia and haemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. The common presenting symptom of subcapsular haematoma is acute-onset upper abdominal pain in patients suffering from preeclampsia; shock is the presenting feature in severe cases of rupture. Here we have discussed a case of subcapsular haematoma associated with HELLP syndrome in a patient who responded to conservative management.

InAs semiconductor quantum dots (QDs) emitting in the near-infrared are promising platforms for on-demand single-photon sources and spin-photon interfaces. However, the realization of quantum-photonic nanodevices emitting in the telecom windows with similar performance remains an open challenge. In particular, nanophotonic devices incorporating quantum light emitting diodes in the telecom C-band based on GaAs substrates are still lacking due to the relaxation of the lattice constant along the InGaAs graded layer which makes the implementation of electrically contacted devices challenging.

Unlabelled: Far removed from the agricultural fire "hotspots" of Northwestern India, rice residue burning is on the rise in Eastern India with implications for regional air quality and agricultural sustainability. The underlying drivers contributing to the increase in burning have been linked to the adoption of mechanized (combine) harvesting but, in general, are inadequately understood. We hypothesize that the adoption of burning as a management practice results from a set of socio-technical interactions rather than emerging from a single factor.

  • Chronic kidney disease (CKD) is becoming more common, particularly in East Asian countries where the incidence of kidney failure is higher compared to Western nations, although the reasons for this are not fully understood.
  • Mutations in the ALDH2 enzyme, common in 35-45% of East Asians, have been linked to various health issues, but its specific role in CKD was previously unclear.
  • Research findings indicate that ALDH2 expression decreases with the progression of CKD, and its deficiency contributes to kidney fibrosis, suggesting that ALDH2 levels could impact the worsening of CKD, specifically in East Asian populations.

Residence time of an element in the ocean is a consequence of its chemical behaviour and the various biogeochemical processes governing its distribution, sources, and sinks. Precise estimation of the residence time of beryllium(Be) is necessary for its application as a tracer for understanding present and paleo-environmental processes. We utilise cosmogenic Be and terrestrially derived Be measurements from surface sediments to estimate the residence time of Be in the Indian Ocean.

The photoelectrochemical photocurrent switching (PEPS) effect to change the photocurrent direction from cathodic to anodic external bias is an important phenomenon. Specifically, tuning the critical state or the potential corresponding to a switchable photocurrent direction through easily controllable parameters is crucial for developing efficient photo-electrocatalyst systems. Although the PEPS effect has been reported in quite a few recently published studies, the changeable critical state has not yet been demonstrated.
