Few studies have reported the effects of lumbar spine mobilization on neurodynamics. In a recent study, Szlezak et al. (2011) reported immediate improvement of posterior chain neurodynamics [range of passive straight leg raise (SLR)] following ipsilateral lumbar spine zygopophyseal (Z) joint mobilization. We re-duplicated the study with a 24 h follow-up measurement. Sixty healthy college students were assigned to two groups, mobilization and control. The mobilization group received ipsilateral grade 3 Maitland mobilizations to Z joint at a frequency of 2 MHz for 3 min and the control group received no treatment. The SLR was measured before and after the intervention for both the groups on the day of testing and 24-h later. Repeated measures ANOVA showed statistically significant pre to post improvement in SLR range after mobilization. The improvement was retained at 24-h. The results of the study are consistent with Szlezak et al. (2011).

The exponential random graph model (ERGM) is a popular model for social networks, which is known to have an intractable likelihood function. Sampling from the posterior for such a model is a long-standing problem in statistical research. We analyze the performance of the stochastic gradient Langevin dynamics (SGLD) algorithm (also known as noisy Longevin Monte Carlo) in tackling this problem, where the stochastic gradient is calculated via running a short Markov chain (the so-called inner Markov chain in this paper) at each iteration.

In the field of medicine, evaluating the diagnostic performance of new diagnostic methods can be challenging, especially in the absence of a gold standard. This study proposes a methodology for assessing the performance of diagnostic tests by estimating the posterior distribution of the score using latent class analysis, without relying on a gold standard. The proposed method utilizes Markov Chain Monte Carlo sampling to estimate the posterior distribution of the score, enabling a comprehensive evaluation of diagnostic test methods.

Bluetongue (BT) is considered endemic in the southern states of India, with sporadic incidences reported from the northern, western and central parts of India. However, the eastern and north-eastern states of India have not experienced active disease so far. In the recent past, an extensive sero-epidemiological investigation was carried out in the eastern and north-eastern Indian states.

Early-onset Alzheimer's disease constitutes ∼5-10% of Alzheimer's disease. Its clinical characteristics and biomarker profiles are not well documented. To compare the characteristics covering clinical, neuropsychological and biomarker profiles between patients with early- and late-onset Alzheimer's disease, we enrolled 203 patients (late-onset Alzheimer's disease = 99; early-onset Alzheimer's disease = 104) from a Chinese hospital-based cohort, the Shanghai Memory Study.

Background: Reversed shoulder arthroplasty (rTSA) is often used to restore functionality in patients with joint arthropathy and dysfunctional rotator cuff. As rTSA changes the biomechanical properties of the shoulder, an altered movement pattern of arm and scapula is to be expected. Previous studies focused on changes of the scapulohumeral rhythm during functional elevation tasks.
