α2δ proteins are important for neurological function and contribute to calcium channel membrane trafficking, although how α2δ proteins influence postsynaptic calcium-dependent signalling is largely unexplored. Here it is shown that loss of α2δ-2 proteins disrupts functional calcium coupling to two different postsynaptic calcium-dependent signals in mouse Purkinje cell neurons, retrograde endocannabinoid signalling and the action potential afterhyperpolarization. The findings provide new insights into the control of calcium coupling as well as new roles for α2δ-2 proteins in neurons.Aging, a time-dependent multifaceted process, affects both cell structure and function and involves oxidative stress as well as glycation. The present investigation focuses on the role of the band 3 protein (B3p), an anion exchanger essential to red cells homeostasis, in a d-galactose ( d-Gal)-induced aging model. Anion exchange capability, measured by the rate constant of SO₄²- uptake through B3p, levels of lipid peroxidation, oxidation of membrane sulfhydryl groups, B3p expression, methemoglobin, glycated hemoglobin (Hb), and the reduced glutathione/oxidized glutathione ratio were determined after exposure of human erythrocytes to 25, 35, 50, and 100 mmol/L d-Gal for 24 h. Our results show that (i) in vitro application of d-Gal is useful to model early aging in human erythrocytes; (ii) assessment of B3p ion transport function is a sensitive tool to monitor aging development; (iii) d-Gal leads to Hb glycation and produces substantial changes on the endogenous antioxidant system; (iv) the impact of aging on B3p function proceeds through steps, first involving Hb glycation and then oxidative events at the membrane level. These findings offer a useful tool to understand the mechanisms of aging in human erythrocytes and propose B3p as a possible target for new therapeutic strategies to counteract age-related disturbances.
Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system, with an unpredictable course. Current MS therapies such as disease-modifying therapies focus on treating exacerbations, preventing new exacerbations and avoiding the progression of disability. Siponimod (BAF312) is an oral treatment, a selective sphingosine-1-phosphate (S1P) receptor modulator, for the treatment of adults with relapsing forms of MS including active, secondary progressive MS with relapses.

To assess the benefits and adverse effects of siponimod as monotherapy or combination therapy versus placebo or any active comparator for people diagnosed with MS.

On 18 June 2020, we searched the Cochrane Multiple Sclerosis and Rare Diseases of the CNS Trials Register, which contains studies from CENTRAL, MEDLINE and Embase, and the trials registry databases ClinicalTrials.gov and WHO International Clinical Trials Registry Platform (ICTRP). We also handsearched relevant journals and screened the reference listse evidence to support the benefit in reducing the number of people with a relapse is very low. The risk of withdrawals due to adverse events requires careful monitoring of participants over time. The duration of all studies was less than 24 months, so the efficacy and safety of siponimod over 24 months are still uncertain, and further exploration is needed in the future. There is no high-certainty data available to evaluate the benefit on MRI outcomes. We assessed the certainty of the body of evidence for all outcomes was low to very low, downgraded due to serious study limitations, imprecision and indirectness. We are uncertain whether siponimod is beneficial for people with MS. More new studies with robust methodology and longer follow-up are needed to evaluate the benefit of siponimod for the management of MS and to observe long-term adverse effects. Also, in addition to comparing with placebo, more new studies are needed to evaluate siponimod versus other therapeutic options.
In Xeroderma Pigmentosum (XP), the main means of preventing skin and eye cancers is extreme protection against ultraviolet radiation (UVR). Protection is most important for the face.

We aimed to assess how well patients with XP adhere to medical advice to protect against UVR by objectively estimating the mean daily dose of UVR to the face.

We objectively estimated the UVR dose to the face in 36 XP patients and 25 healthy individuals over 3 weeks in the summer. We used a new methodology which combined UVR dose measurements from a wrist-worn dosimeter with an activity diary record of face photoprotection behaviour for each 15 minute period spent outside. A protection factor was associated with each behaviour, and the data analysed using a negative binomial mixed-effects model.

The mean daily UVR dose (weighted for DNA damage capacity) to the face in the XP patients was 0.13 Standard Erythemal Doses (SED) (mean in healthy individuals = 0.51 SED). There was wide variation between patients (range <0.01 e face. This new methodology will be of value in identifying the sources of UVR exposure in other conditions where facial UV exposure is a key outcome, particularly in patients with multiple non-melanoma skin cancers.
This study investigated the lumbosacral plexus (LSP) nerve root thickness and ligamentum flavum (LF) thickness and correlated them with age and sex. These findings provided a useful data for spinal nerve root micro-anastomosis surgery and lumbar decompression surgery.

This retrospective study was conducted with 350 individuals with ages ranging from 21 to 80 years of age under magnetic resonance imaging (MRI) to evaluated the possible cause of a lower back pain.

According to the morphometric measurements of the LSP root thickness, the diameter gradually increased from L1 to S1. L1 has the thinnest root (3.9 ± 0.81 mm) while S1 has the thickest root (5.45 ± 0.8 mm). The measurements revealed inconsiderable differences in the LSP thickness in relation to age, sex in the study population. Regarding the LF, the thickness of the LF was found to be insignificantly increase with age. Besides, the LF thickness was inconsequentially higher in female. The mean thickness of the right LF at different spinal levels was measured (L2-L3 = 3.19 ± 0.27, L3-L4 = 3.38 ± 0.11 mm, L4-L5 = 3.71 ± 0.29 mm, and L5-S1 = 3.64 ± 0.21 mm). The mean thickness of the left LF was non significantly higher.

The etiology can be related to repetitive exposure to vibrations or forceful angular motions, genetic predisposition, injury and specific conditions, such as diabetes, pregnancy and morbid obesity. This entity is observed with increased frequency in females and the elderly. The diagnosis is largely clinical and suspected when patients present with typical symptoms such as numbness, tingling, nocturnal paresthesiae and/or neuritic "pins-and-needles" pain in the radial 3.5 digits. Certain provocative manoeuvres can be employed to evoke the symptoms of the disease to guide the diagnosis. Further testing such as electrodiagnostic studies, ultrasound or magnetic resonance imaging is required in the case of diagnostic uncertainty or if there is a need for objective evaluation whether or not more invasive surgical intervention is required. If the presenting symptoms are mild and discontinuous, non-surgical measures are indicated. However, if the symptoms are moderate to severe, further testing modalities such as nerve conduction studies or needle electromyography are used to determine whether carpal tunnel syndrome is acute or chronic. If significant evidence of axonal injury is identified, surgical treatment may be indicated. Surgical release of the carpal tunnel has evolved over time to become the most common hand surgery procedure.The biceps brachii is located in the anterior compartment of the arm, which can show numerous morphological variations. During anatomical dissection, an interesting additional muscle was found the third head of the biceps brachii originated from the short head of the same muscle. The 97.77 mm long muscle belly was directed medially over the arm and then passed into the common tendon (15.97 mm), which thereafter split into aponeurosis and tendon. The 26.33 mm aponeurosis passed and joined the fascia of the forearm. The tendon of the third head of the biceps brachii then gave rise to the ulnar head of the pronator teres muscle. Such an accessory structure could cause neurovascular compression involving the brachial artery and median nerve. Knowledge of the morphological variability of this region is essential not only for anatomists but also for clinicians.
To investigate the impact of fetal-type posterior cerebral artery (fPCA) variant on morphological parameters of posterior communicating artery (PComA) aneurysms for rupture risk assessment.

A total of 98 PComA aneurysms (62 ruptured and 36 unruptured) in 98 consecutive patients were reviewed. Morphological parameters were calculated including aneurysm size, aspect ratio (AR), size ratio (SR), dome-to-neck ratio (DN), bottleneck factor (BNF) and inflow angle. Performance of morphological parameters to discriminate rupture status were compared between aneurysms with or without fPCA.

fPCA variant was determined in 39 (39.8%, 25 ruptured and 14 unruptured) lesions. The ruptured group revealed a significantly larger size (P=0.004), AR (P=0.003), SR (P=0.001), and inflow angle (P<0.001). For the aneurysms without fPCA, all morphological parameters were significantly different between ruptured and unruptured aneurysms (P<0.05); for the aneurysms with fPCA, only inflow angle (P=0.001) was significantly related with the rupture status. Multivariate analysis showed that SR (P=0.035 and P=0.011) and inflow angle (P=0.001 and P=0.028) were independent rupture risk factors for the total cohort and the aneurysms without fPCA; while only inflow angle (P=0.004) revealed to be independently related with rupture status of aneurysms without fPCA.

The performance of morphological parameters to discriminate rupture status were different between PComA Aneurysms with and without fPCA variants. Inflow angle might be a reliable predictor for rupture risk of PComA aneurysms.

Both eyes had Bitot's spots and ulceration. The right cornea had a perforation at admission. After treatment with high doses of vitamin A the right cornea epithelialized with formation of the anterior chamber and the left eye healed completely. This case adds to the increasing number of reports on cases of xerophthalmia particularly in autistic children and highlights the importance of considering vitamin A deficiency in patients with risk of malnutrition also in developed countries.
