These changes were mediated by a shift to non-amyloidogenic cleavage of the human amyloid precursor protein (APP), recovery of the neurovascular unit and maintaining microglial metabolic fitness. Mechanistically, Klk8-knockdown improved Aβ phagocytosis in primary glia and Aβ resistance in primary neurons. Most importantly, transgenic mice revealed less anxiety and a better memory performance.

These results reinforce the potential of KLK8 as a therapeutic target in AD.

C-reactive protein (CRP) and paraoxonase 1 (PON1) might increase and decrease in canine leishmaniasis (CanL), , and both can rapidly normalize after therapy. Recently, supplementation of domperidone with conventional therapy , increasing the activity of cells involved in acute phase responses in vitro. This combined therapy has been recommended to treat mild forms of CanL; however, no studies have investigated the effects of domperidone supplementation on early CRP or PON1 changes in dogs with CanL.

The aim of this study was to evaluate whether domperidone, added to conventional treatments, modifies CRP concentration and PON1 activity kinetics in CanL dogs responsive to conventional therapy.

Serum CRP concentrations and PON1 activities were measured in dogs with mild CanL before (t-0) and 3 (t-1), 7 (t-2), 14 (t-3), and 21 (t-4) days after treatment with N-methylglucamine antimoniate and allopurinol alone (n=18) or combined with domperidone (n=18).

C-reactive protein concentrations increased at t-1 in the domperidone group, especially when the CRP concentration at t-0 was normal. However, the concentrations normalized at t-4 in 18/18 dogs compared with 14/18 dogs not receiving domperidone. The median PON1 activity decreased at t-1 in the domperidone group, and this decrease was more significant in dogs with normal PON1 activity at t-0.

Based on these results, transient increases in CRP concentrations or decreases in PON1 activities after domperidone administration should not be erroneously interpreted as signs of a worsening disease process.

We review emerging techniques that use the axonal transport of adeno-associated virus (AAV) vectors to dissect neural circuits. These intersectional approaches specifically target AAV-mediated gene expression to discrete neuron populations based on their axonal connectivity, including (a) neurons with one defined output, (b) neurons with one defined input, (c) neurons with one defined input and one defined output, and (d) neurons with two defined inputs or outputs. The number of labeled neurons can be directly controlled to trace axonal projections and examine cellular morphology. These approaches can precisely target the expression of fluorescent reporters, optogenetic ion channels, chemogenetic receptors, disease-associated proteins, and other factors to defined neural circuits in mammals ranging from mice to macaques, and thereby provide a powerful new means to understand the structure and function of the nervous system.

Tinea capitis is a highly contagious infectious disease caused by dermatophytes. In Central Europe, it is mainly caused by zoophilic dermatophytes, as, for example Microsporum (M) canis or Trichophyton (T) mentagrophytes and increasingly by anthropophilic fungi. Ttonsurans was commonly related to the Tinea gladiatorum, where transmission occurred between infected persons or via contaminated floors.

Reporting the transmission of this highly contagious dermatophyte for the first time via beard shaving and hairdressing in barber shops in Germany.

18 young male patients developed tinea capitis and/or barbae shortly after shavings of the beard and/or hair in a barber shop. Native, cultural and molecular diagnostics as well as tissue biopsies and resistance tests were performed of skin and hair samples.

In all samples, Ttonsurans could be identified. The medical history and the clinical picture suggest a transmission through contaminated hairdressing tools. The patients were treated with terbinafine or itraconazole in combination with or exclusively with topical antimycotics.

The transmission and a resulting increase in the incidence of infections with Ttonsurans may be due to shavings with direct skin contact of insufficiently disinfected hairdressing tools. This path of infection has already been observed in Africa and is now being described for the first time in Germany. Knowledge of the pathogen and its transmission ways are essential to interrupt the chain of infection.

The Food Standards Agency, biennial Food and You Survey of adults aged 16 years and over living in the UK, found that between 2012 and 2018 the proportion of people who reported never consuming dairy products had increased from 2% to 5%. However, veganism risks development of vitamin B12 deficiency as it is not available from plant sources. Moreover, its impact may be slow to be detected because body stores of vitamin B12 can last years. There is currently no published guidance on antenatal diagnosis and management of vitamin B12 deficiency. This paper reviews the metabolism, diagnosis and treatment of vitamin B12 in pregnancy. It concludes that national screening policymakers should consider introducing screening for B12 deficiency into the Antenatal and Newborn Screening Programmes for mothers and their infants if at risk of vitamin B12 deficiency. In the interim, national policy should be developed for prophylactic vitamin B12 supplementation in high-risk groups around the time of pregnancy.
