The three dimensional (3D) innervation zone (IZ) imaging approach (3DIZI) has been developed in our group to localize the IZ of a particular motor unit (MU) from its motor unit action potentials decomposed from high-density surface electromyography (EMG) recordings. In this study, the developed 3DIZI approach was combined with electrical stimulation to investigate global distributions of IZs in muscles from electrically elicited M-wave recordings. Electrical stimulations were applied to the musculocutaneous nerve to activate supramaximal muscle response of the biceps brachii in one healthy subject, and high-density (128 channels) surface EMG signals of the biceps brachii muscles were recorded...

"Onabotulinum toxin A (Botox) revolution" has brought the fundamental change in the facial rejuvenation as well as the concept of microinjection. The aesthetic standard tends to be the "globalization"; however, Asians have different aesthetic cultures and unique facial features compared with Caucasians. A new rejuvenation concept is proposed during our practice; the Asian face should preserve the original facial identity during Botox treatments. The lower face is treated with botulinum toxin to achieve a harmonious facial profile...

The first reported application of Botulinum toxin-A (BTX-A) into the urethral sphincter predates the first documented use in the bladder. The aim of this review is to describe the clinical indications of BTX-A injection into the urethral sphincter and its clinical efficacy. This review of the literature includes the larger more significant published studies that have reported on this use of BTX-A. Case reports and articles not published in English were excluded. There have been many published clinical studies describing the use of BTX-A in the urethral sphincter, four of which are randomized placebo controlled trials...

Botulinum toxin (Botox) is an exotoxin produced from Clostridium botulinum. It blocks the release of acetylcholine from the cholinergic nerve end plates resulting in inactivity of the muscles or glands innervated. The efficacy of Botox in facial aesthetics is well established; however, recent literature has highlighted its utilization in multiple non-cosmetic medical and surgical conditions. The present article reviews the current evidence pertaining to Botox use in the non-cosmetic head and neck conditions...

Botulinum neurotoxin (BoNT) binds to and internalizes its light chain into presynaptic compartments with exquisite specificity. While the native toxin is extremely lethal, bioengineering of BoNT has the potential to eliminate toxicity without disrupting neuron-specific targeting, thereby creating a molecular vehicle capable of delivering therapeutic cargo into the neuronal cytosol. Building upon previous work, we have developed an atoxic derivative (ad) of BoNT/C1 through rationally designed amino acid substitutions in the metalloprotease domain of wild type (wt) BoNT/C1...

Chronic hyperglycemia (HG) promotes pancreatic islet dysfunction which leads to the onset of T2DM. This study is aimed at defining regulatory roles of Rac1, a small G-protein, in the activation of p53 and ATM kinase in pancreatic β-cells, under the duress of HG conditions. We report significant stimulatory effects of HG (20 mM; 24 h) on p53 activation in INS-1 832/13 cells, normal rodent and human islets. Pharmacological inhibition of Rac1 (EHT1864 or NSC23766) significantly suppressed HG-induced p53 activation in INS-1 832/13 cells and rat islets, suggesting novel roles for this small G-protein in the activation of p53...

Pathogenic clostridia typically produce toxins as virulence factors which cause severe diseases in both humans and animals. Whereas many clostridia like e.g., Clostridium perfringens, Clostridium botulinum or Clostridium tetani were shown to contain toxin-encoding plasmids, only toxin genes located on the chromosome were detected in Clostridioides difficile so far. In this study, we determined, annotated, and analyzed the complete genome of the bacteriophage phiSemix9P1 using single-molecule real-time sequencing technology (SMRT)...

REVIEW
Angela M Arlen
PURPOSE OF REVIEW: Dysfunctional voiding is defined as "habitual contraction of the urethral sphincter during voiding." Children with dysfunctional voiding remain a challenge, and the approach to and management of LUT dysfunction varies widely among programs and providers with the role of pharmacotherapy being ill defined. RECENT FINDINGS: Animated biofeedback is the current treatment modality of choice in children who are not responsive to standard urotherapy. Comprehensive biofeedback programs incorporate continued elimination education, voiding diaries, and home exercises with high success rates...

Facial scaring is considered one of the most difficult cosmetic problems for any plastic surgeon to solve. The condition is more difficult if the direction of the scar is not parallel to relaxed skin tension lines. Attempts to manage this difficult situation included revisions using geometric designs, Z plasties or W plasties to camouflage the straight line visible scaring. The use of long-lasting resorbable sutures was tried too. Recently, the use of botulinum toxin during revision improved the results. Fractional CO2 lasers, microfat grafts, and platelet-rich plasma were added to the armamentarium...

Combination therapies targeting multiple recovery mechanisms have the potential for additive or synergistic effects, but experimental design and analyses of multimodal therapeutic trials are challenging. To address this problem, we developed a data-driven approach to integrate and analyze raw source data from separate pre-clinical studies and evaluated interactions between four treatments following traumatic brain injury. Histologic and behavioral outcomes were measured in 202 rats treated with combinations of an anti-inflammatory agent (minocycline), a neurotrophic agent (LM11A-31), and physical therapy consisting of assisted exercise with or without botulinum toxin-induced limb constraint...

Bruxism (teeth grinding) is an under-recognized cause of caregiver concern in patients with Alzheimer's disease. We report two cases of Alzheimer's disease with bruxism that caused significant distress to the caregivers. Patient data were collected from the case records of our hospital. One patient presented with early Alzheimer's disease and another with advanced Alzheimer's disease had bruxism causing significant caregiver distress. One patient was treated with botulinum toxin type A with complete relief of the symptom...

Today, innovative restorative materials and techniques allow for minimally invasive prosthetic procedures, which are paramount to the preservation of hard and soft dental tissues. An integrated approach combining dental and esthetic medical therapies could be useful to improve the quality of life of patients, improving function, esthetics, and self-confidence. Oral esthetics depends on several variables, including tooth visibility and proportions as well as healthy gingival tissues. Proper integration between teeth and periodontal tissues plays an important role in esthetic success, which is mainly represented by an appealing smile...

Sialorrhoea is a common and problematic symptom that arises from a range of neurological conditions associated with bulbar or facial muscle dysfunction. Drooling can significantly affect quality of life due to both physical complications such as oral chapping, and psychological complications such as embarrassment and social isolation. Thicker, tenacious oral and pharyngeal secretions may result from the drying management approach to sialorrhoea. The management of sialorrhoea in neurological diseases depends on the underlying pathology and severity of symptoms...
