Notes

Aberrant term involving SNHG12 leads to N, N-dimethylformamide-induced hepatic apoptosis in the short-term and long-term DMF direct exposure.
Aetiological diagnosis in non-syndromic intellectual disability (NSID) still poses a diagnostic challenge to clinicians.

Screening is currently achieved by chromosomal microarrays followed by whole-exome sequencing (WES). In search for the aetiological yield of WES in patients with NSID, 59 unrelated patients were studied.

Among the 59 patients, 44 (74.6%) were from consanguineous unions. Epilepsy was present in 11 (37.9%), behavioural problems in 12 (41.4%) and autistic features in 14 (48.3%). WES analysis resulted in molecular diagnosis in 29 patients (49.2%). Some of the genes were specific for nervous system functioning, like HERC1, TBC1D7, LINS, HECW2, DEAF1, HNMT, DLG3, NRXN1 and HUWE1. Others were ubiquitously expressed genes involved in fundamental cellular processes, like IARS, UBE3A, COQ4, TAF1, SETBP1, ARV1, ZC4H2, KAT6A, ASXL3, THOC6, HNRNPH2, TUBA8 and KIF1A. Twenty-two (75.8%) were consanguineously married; however, only 12 (41.4%) of the detected genes caused autosomal recessive phenotypes.

This cohort suggests that recessive genes probably represent an actually smaller subgroup of NSID, even among families with consanguinity. Although in societies with high consanguinity rates, considering the recessive inheritance first seems to be an advantageous strategy, de novo mutations in autosomal dominantly expressed genes represent the major aetiological group in patients with NSID, even among those patients from consanguineous families.

To study whether the preparation procedure, and its acidic and heating conditions, used by heroin users to prepare heroin for intravenous administration affects the final composition of the fluid to be injected.

Samples from different seizures of illegal heroin provided by the Norwegian police were prepared by adding water and ascorbic acid before heating under controlled conditions in the laboratory. Further, three seizures were prepared with different amounts of ascorbic or citric acid relative to their diacetylmorphine content. Pure diacetylmorphine base or salt was also submitted to the procedure applying two different heating intensities. The seizures and the final product after preparation were analysed for diacetylmorphine, 6-acetylmorphine and morphine using liquid chromatography with tandem mass spectrometry (LC-MS-MS).

After preparation, a decrease of 19.8% (25th and 75th percentiles=-29.2 and -15.3) in the initial diacetylmorphine content was observed. Both the 6-acetylmorphine and morphine ccted solution, and therefore affect the outcome after injection.
Preparation of heroin for intravenous injection appears to change the amount or concentration of diacetylmorphine and its active metabolites, 6-acetylmorphine and morphine in the final product, depending on heroin purity, amount and type of acid used or heating conditions. SGI-1027 supplier These circumstances can contribute to unintentional variations in the potency of the final injected solution, and therefore affect the outcome after injection.
Southern sea otters (Enhydra lutris nereis) rely on intact pelage for thermoregulation, and thus clinically significant demodicosis and associated alopecia can cause morbidity and death.

This study aimed to describe lesions associated with follicular Demodex sp. infestation, estimate the prevalence and intensity of infestation, describe mite distribution across key anatomical regions, and assess mite presence or absence in relation to lesions and host risk factors.

Twenty necropsied, wild southern sea otters that stranded along the central California coast from 2005 to 2018.

Grossly normal and abnormal integument from the head, perineum, genitals, mamillary papillae and limbs was assessed microscopically for mites and mite-associated pathological findings.

Intrafollicular mites were observed in the integument of 55% of otters and 20% had clinical demodicosis. Demodicosis was considered to be contributory to death or euthanasia in two cases. Although Demodex sp. mites often were observed microscopically in grossly normal skin, the presence of multiple densely-packed intrafollicular mites generally was associated with pigmentary incontinence, ectatic follicles, lymphoplasmacytic perifolliculitis, and neutrophilic and lymphoplasmacytic, dermal inflammation. Other findings included epidermal hyperplasia, orthokeratotic hyperkeratosis of epidermis and follicular epithelium, concurrent pyoderma and cell necrosis. Perioral integument, especially of the chin, had the highest prevalence of mites and the highest mite density, suggesting facial contact as a means of mite transmission.

Our research confirmed demodectic mange as a contributor to morbidity and mortality in sea otters, with important implications for clinical care, rehabilitation and conservation.
Our research confirmed demodectic mange as a contributor to morbidity and mortality in sea otters, with important implications for clinical care, rehabilitation and conservation.This study is an observational study that takes the existing longitudinal data from Alzheimer's disease Neuroimaging Initiative to examine the spatial correlation map of hippocampal subfield atrophy with CSF biomarkers and cognitive decline in the course of AD. This study included 421 healthy controls (HC), 557 patients of stable mild cognitive impairment (s-MCI), 304 Alzheimer's Disease (AD) patients, and 241 subjects who converted to be AD from MCI (c-MCI), and 6,525 MRI scans in a period from 2004 to 2019. Our findings revealed that all the hippocampal subfields showed their accelerated atrophy rate from cognitively normal aging to stable MCI and AD. The presubiculum, dentate gyrus, and fimbria showed greater atrophy beyond the whole hippocampus in the HC, s-MCI, and AD groups and corresponded to a greater decline of memory and attention in the s-MCI group. Moreover, the higher atrophy rates of the subiculum and CA2/3, CA4 were also associated with a greater decline in attention in the s-MCI group. Interestingly, patients with c-MCI showed that the presubiculum atrophy was associated with CSF tau levels and corresponded to the onset age of AD and a decline in attention in patients with c-MCI.
