Autonomic dysreflexia （AD） is a serious cardiovascular disorder in patients with spinal cord injury （SCI）. The primary underlying cause of AD is loss of supraspinal control over sympathetic preganglionic neurons （SPNs） caudal to the injury, which renders the SPNs hyper-responsive to stimulation. Central maladaptive plasticity, including C-fiber sprouting and propriospinal fiber proliferation exaggerates noxious afferent transmission to the SPNs, causing them to release massive sympathetic discharges that result in severe hypertensive episodes. In parallel, upregulated peripheral vascular sensitivity following SCI exacerbates the hypertensive response by augmenting gastric and pelvic vasoconstriction. Currently, the majority of clinically employed treatments for AD involve anti-hypertensive medications and Botox injections to the bladder. Although these approaches mitigate the severity of AD, they only yield transient effects and target the effector organs, rather than addressing the primary issue of central sympathetic dysregulation. As such, strategies that aim to restore supraspinal reinnervation of SPNs to improve cardiovascular sympathetic regulation are likely more effective for AD. Recent pre-clinical investigations show that cell transplantation therapy is efficacious in reestablishing spinal sympathetic connections and improving hemodynamic per- formance, which holds promise as a potential therapeutic approach.

We investigated the resistance of acetylated rattan against soft rot and other soil inhabiting micro-organisms in comparison with wood of beech and Scots pine. Calamus manan of 10 and 13 years old under rubber tree canopy was acetylated to different levels by reaction times （0.25 to 30 hours） and was tested for soft rot decay for 32 weeks. Acetylated rattan at decay protection thresholds of 15.4% and 16.2% weight gain （WG） were fully protected, as shown by both weight loss and strength loss criteria. The static bending properties of untreated rattan decayed by soft rot were significantly lower than for acetylated rattan.

Objective: To apply office hysteroscopy in assessment/management of patients with recurrent miscarriage, thus to/or not to recommend office hysteroscopy as a routine procedure in such cases. Study design: Retrospective analysis. Setting: University hospital’s outpatient abortion clinic. Subjects & Methodology: Patients’ records during the period between March 2015 and January 2017 for subjects with at least 2 previous miscarriages, who had undergone office hysteroscopy were reviewed. Results: Cases with 2 previous miscarriages (n = 95) were assessed and compared with those with 3 or more miscarriages (n = 105). Abnormal uterine findings were diagnosed in 24.1% of the former, and 43.8% of the latter group. The prevalence of uterine lesions among cases with 2 recurrent miscarriages was 42.1%;meanwhile, for subjects with 3 or more consecutive miscarriages, it was 43.8%. Conclusion: In addition to safety profile, simplicity and outpatient basis of use, outpatient hysteroscopy in recurrent miscarriages would be an added-value to practitioners as a diagnostic and therapeutic tool.

A generalized continuity equation extending the ordinary continuity equation is found using quanternions to show it is compatible with Dirac, Schrǒdinger, Klein-Gordon and diffusion equations. This generalized equation is Lorentz invariant. The transport properties of electrons are found to be governed by the Schr6dinger-like equation and not by the diffusion equation.
