Acetyl-L-carnitine for the treatment of diabetic peripheral neuropathy.

BACKGROUND: Diabetic peripheral neuropathy (DPN) is a common and severe complication that affects 50% of people with diabetes. Painful DPN is reported to occur in 16% to 24% of people with diabetes. A complete and comprehensive management strategy for the prevention and treatment of DPN, whether painful or not, has not yet been defined.Research into treatment for DPN has been characterised by a series of failed clinical trials, with few noteworthy advances. Strategies that support peripheral nerve regeneration and restore neurological function in people with painful or painless DPN are needed.

Effect of brain- and tumor-derived connective tissue growth factor on glioma invasion.

BACKGROUND: Tumor cell invasion is the principal cause of treatment failure and death among patients with malignant gliomas. Connective tissue growth factor (CTGF) has been previously implicated in cancer metastasis and invasion in various tumors. We explored the mechanism of CTGF-mediated glioma cell infiltration and examined potential therapeutic targets. METHODS: Highly infiltrative patient-derived glioma tumor-initiating or tumor stem cells (TIC/TSCs) were harvested and used to explore a CTGF-induced signal transduction pathway via luciferase reporter assays, chromatin immunoprecipitation

Subacromial Balloon Spacer: Indications, Rationale, and Technique.

UNLABELLED: Irreparable rotator cuff tears are those that cannot be restored back to their native footprint or those in which any repair will "almost certainly" lead to a structural failure as a result of poor tissue quality, degeneration, or retraction1-3. The InSpace subacromial balloon spacer (Stryker) was developed as a temporary spacer to restore anatomic relationships between the glenoid, humerus, and acromion to improve function and reduce pain associated with this challenging pathology. DESCRIPTION: First, a diagnostic arthroscopy is performed. In addition to evaluating the rotator cu

[A 56-year-old man with fever, backache and tetraparesis].

We report a 56-year-old man who developed progressive paraparesis. He was apparently well, except for left Bell's palsy which developed on May 9 of 1994, for which he received stellate ganglion block on the left side more than ten times until July 2nd of 1994, when he noted pain in his left shoulder and in his lumbar region. On July 5th, he noted some difficulty in urination. On July 6th, he noted tingling sensation in his four extremities and difficulty in gait. He was admitted to another hospital where he was treated with intravenous infusion of glycerol. After this treatment, his gait and s

Efficient in vivo protection of nigral dopaminergic neurons by lentiviral gene transfer of a modified Neurturin construct.

Protein injection studies of the glial cell line derived neurotrophic factor (GDNF) family member Neurturin (NTN) have demonstrated neuroprotective effects on dopaminergic (DA) neurons, which are selectively lost during Parkinson's disease (PD). However, unlike GDNF, NTN has not previously been applied in PD models using an in vivo gene therapy approach. Difficulties with lentiviral gene delivery of wild type (wt) NTN led us to examine the role of the pre-pro-sequence, and to evaluate different NTN constructs in order to optimize gene therapy with NTN. Results from transfected cultured cells s

Evans and Cotton Osteotomies Using Porous Titanium Wedges to Correct Pediatric Flatfoot Deformity.

BACKGROUND: The present video article demonstrates the use of Evans and Cotton osteotomies with porous titanium wedges for the treatment of pediatric flatfoot. Pediatric flatfoot is not commonly painful or disabling and usually resolves as the arch elevates spontaneously. However, in cases of flatfoot that persist despite nonoperative treatment, symptoms such as severe activity-related pain and medial foot calluses are an indication for surgical intervention3. The aims of treatment in pediatric patients are to correct anatomical deformity and reduce pain while maintaining mobility. DESCRIPTIO

EXPERIMENTS WITH POLIOMYELITIS IN THE RABBIT.

The poliomyelitic virus obtained from an experimental monkey has been passed through eight generations in rabbits. It shows no signs of dying out. On the other hand, it gives no evidence of becoming more pathogenic to the species through successive passage. The period of incubation remains variable and the percentage of takes has not increased. Whether eventually a virus can be obtained which is of heightened virulence to rabbits is problematic. All inoculations are by no means successful. The animals show great individual differences in susceptibility to the virus, as is evidenced by the fact

Press-Fit Bone-Anchored Prosthesis for Individuals with Transtibial Amputation.

BACKGROUND: This video article describes the use of bone-anchored prostheses for patients with transtibial amputations, most often resulting from trauma, infection, or dysvascular disease. Large studies have shown that about half of all patients with a socket-suspended artificial limb experience limited mobility and limited prosthesis use because of socket-related problems. These problems occur at the socket-residual limb interface as a result of a painful and unstable connection, leading to an asymmetrical gait and subsequent pelvic and back pain. In almost all of these cases, a bone-anchored

Fundamental structural aspects and features in the bioengineering of the gas exchangers: comparative perspectives.

Over its life, an organism's survival and success are determined by the inventory of vital adaptations that its progenitors have creatively appropriated, devised and harnessed along the evolutionary pathway. Such conserved attributes provide the armamentarium necessary for withstanding the adverse effects of natural selection. Refinements of the designs of the respiratory organs have been critical for survival and phylogenetic advancement of animal life. Gas exchangers have changed in direct response to the respiratory needs of whole organisms in different environmental states and conditions.

Бета Адренергическая сигнализация как терапевтическая цель для автономного иммунитета.

Мы недавно определили молекулярный механизм с использованием бета-адренергических рецепторов 1 и 2 (β1/2) при разработке лимфоцитов TH17. Фармакологические и генетические ингибиции этих рецепторов в сочетании, но не отдельно, сказались на способности Т-лимфоцитов производить профламматический интерleукин 17А (IL-17A) и вместо этого способствовали производству защитных клеток Трега, которые скрывают инфлюкин-10 (IL-10). Вместе с тем остается неясным, может ли этот механизм регулирования использоваться в качестве нового терапевтического подхода к аутоиммунным расстройствам при посредничестве Т-л

Progress and research trends in neurogenic bladder after spinal cord injury bibliometric analysis based on web of science database: An observational study.

Neurogenic bladder (NB) is a significant complication that often occurs after spinal cord injury. It results from urinary dysfunction caused by the injury, disrupting the normal neural control of the bladder and urethra. Symptoms of NB can include urinary frequency, urgency, incontinence, and retention, all of which can greatly impact the quality of life of affected individuals. While there are articles and reviews on NB, fewer specifically address NB following spinal cord injury. This study examined 1095 publications from January 1, 2000, to March 27, 2024, in the Web of Science core database

Exploring Human Brain Metabolism via Genome-Scale Metabolic Modeling with Highlights on Multiple Sclerosis.

Cerebral dysfunctions give rise to a wide range of neurological diseases due to the structural and functional complexity of the human brain stemming from the interactive cellular metabolism of its specific cells, including neurons and glial cells. In parallel with advances in isolation and measurement technologies, genome-scale metabolic models (GEMs) have become a powerful tool in the studies of systems biology to provide critical insights into the understanding of sophisticated eukaryotic systems. In this study, brain cell-specific GEMs were reconstructed for neurons, astrocytes, microglia,

Peripheral Nerves in Cancer: Regulatory Roles and Therapeutic Strategies.

Cancer neuroscience has emerged as a transformative frontier in oncology research, focusing on the interplay between cancer cells and the nervous system. Cancer cells establish tumorspecific neural networks within tumor tissues via neurotrophic hijacking. The nervous system regulates tumor initiation, progression, and metastasis either directly by regulating signal transduction in tumor cells or indirectly by modulating the tumor microenvironment (TME). The positive feedback loop between cancer cells and nerves promotes tumor progression. Deciphering the regulatory role of nerves in tumor prog

Нейростероиды и неврологические расстройства.

Нейростероиды играют важную роль в качестве эндогенных нейромодуляторов, которые производятся на местном уровне в центральной нервной системе и быстро изменяют взрываемость нейронов и активацию микроглиальных клеток и астроцитов. Здесь мы рассматриваем механизмы синтеза, метаболизма и действия нейростероидов в центральной нервной системе. Нейростероиды могут играть различные роли в центральной нервной системе в физиологических условиях, связывая их с мембранными ионными каналами и рецепторами, такими, как рецепторы гамма-аминобутирной кислоты типа А, рецепторы Nметил-D-асортатных рецепторов, к

Ткани головного мозга человека, полученные в результате вскрытия, а также образцы мышц и нерва, полученные в результате биопсии, являются необходимыми ресурсами для изучения патомеханизма нервно-психических расстройств. В этом исследовании мы представляем " Нервусовый системный тканевый банк " Университета Дебрецена, который содержит формализованные и формализованные образцы головного мозга с парафинами (FFPE), а также образцы замороженного нерва и мышечной биопсии. Была создана база данных, содержащая клинические и патологические параметры. В случае вскрытия были зарегистрированы сл

A new approach to characterize postural deficits in chemotherapy-induced peripheral neuropathy and to analyze postural adaptions after an exercise intervention.

BACKGROUND: Postural instability presents a common and disabling consequence of chemotherapy-induced peripheral neuropathy (CIPN). However, knowledge about postural behavior of CIPN patients is sparse. With this pilot study, we used a new approach to i) characterize postural impairments as compared to healthy subjects, ii) allocate possible abnormalities to a set of parameters describing sensorimotor function, and iii) evaluate the effects of a balance-based exercise intervention. METHODS: We analyzed spontaneous and externally perturbed postural control in eight CIPN patients before and afte
