Cell atlas of CCl -induced progressive liver fibrosis reveals stage-specific responses.

Chronic liver injury leads to progressive liver fibrosis and ultimately cirrhosis, a major cause of morbidity and mortality worldwide. However, there are currently no effective anti-fibrotic therapies available, especially for late-stage patients, which is partly attributed to the major knowledge gap regarding liver cell heterogeneity and cell-specific responses in different fibrosis stages. To reveal the multicellular networks regulating mammalian liver fibrosis from mild to severe phenotypes, we generated a single-nucleus transcriptomic atlas encompassing 49 919 nuclei corresponding to all main liver cell types at different stages of murine carbon tetrachloride (CCl )-induced progressive liver fibrosis.

A case report of abdominal distention caused by herpes zoster.

Gastrointestinal complications caused by herpes zoster are extremely rare. Here, we described a case of abdominal distention caused by herpes zoster. The patient was a 59-year-old female who suffered from unexplained paroxysmal and a burning pain on the right part of her waist and abdomen, accompanied by abdominal distention.

Phosphor converted LEDs with omni-directional-reflector coating.

A packaging scheme utilizing omni-directional reflective (ODR) optical coating is described to enhance the light extraction of near UV excited, phosphor-converted LEDs. A simple 1D model was developed to analyze the spectra of the extracted light measured with an integration-sphere as a function of phosphor layer concentration and thickness. Quantitative determination of the absorption coefficients at the pump and fluorescent light wavelength along with the conversion coefficient of phosphors were obtained.

[Effects of transcranial magnetic stimulation on recovery of neural functions and changes of synaptic interface and dendritic structure in the contralateral brain area after cerebral infarction: experiment with rats].

Objective: To evaluate the effects of transcranial magnetic stimulation (TMS) on the brain plasticity and its role in functional outcome in cerebral infarction.

Methods: Twenty male SD rats underwent suture of the unilateral middle cerebral artery (MCA) so as to establish focal cerebral infarction models and then were randomly divided into 2 equal groups: model group, to be reared in the original living state, and TMS group, given in addition TMS treatment 1 day after infarction 2 times per day and 30 pulses per time for 4 weeks. Twenty-eight days after the rats were killed.
