Progressive multifocal leukoencephalopathy (PML) is an opportunistic central nervous system infection caused by the human polyomavirus 2, leading to demyelination from oligodendrocyte death and rapid neurologic decline. Most commonly, PML affects patients in immunocompromised states. However, rare reports of PML in an immunocompetent host exist. Here, we report two cases of PML in older individuals with chronic kidney disease (CKD). CKD can ultimately lead to immune system dysfunction and place patients in a relatively immunosuppressed state. Testing for JC virus should remain a consideration for rapid, unexplained neurologic decline even without known immunocompromised status in the appropriate clinical setting.
Parkinson's disease (PD) is the most common neurodegenerative movement disorder of aging. Its cause is unknown. Current evidence supports a stress-diathesis model of pathogenesis whereby some yet-to-be identified environmental trigger conspires with a permissive genetic background to initiate the disease process. Based on neuropathological observations in other neurodegenerative diseases, such as chronic traumatic encephalopathy where pathological protein aggregates form in close association with damaged blood vessels, investigators have hypothesized that the environmental trigger resides in the bloodstream. As a corollary of this hypothesis, investigators propose that the PD pathological process begins in the brain of affected individuals only after disruption of the blood brain barrier (BBB), thereby allowing access of the inciting agent to nigrostriatal axon terminals in the neostriatum. This forms the foundation for the investigators' hypothesis that the BBB in the neostriatum of PD patients is disrupted. Indeed, in a post-mortem study, investigators demonstrated histopathological evidence for significant striatal BBB disruption in sections of striatum from PD subjects relative to age-matched controls. Critics of this study indicate that post-mortem effects may result in artefactual disruption of the BBB, calling into question the validity and relevance of this potentially important finding to PD pathogenesis and progression. Therefore, investigators are performing this imaging study of live PD patients as a follow-up of their convincing post-mortem study to definitively establish whether BBB dysfunction is a feature of PD.

The neostriatal BBB is dysfunctional in PD patients relative to controls and this can be demonstrated by significantly increased parenchymal enhancement on magnetic resonance imaging (MRI).

The results of these studies could have important implications for the understanding of PD pathogenesis. There is emerging evidence that the key pathogenetic event in PD pathogenesis, aggregation of alpha-synuclein, begins within the axon terminals of neurons. The neurons most severely affected in PD reside in the substantia nigra and project to the neostriatum. Demonstrating disruption of the BBB in the PD striatum would render nigrostriatal axon terminals susceptible to a blood-borne disease trigger and allow researchers to generate hypotheses regarding the identity of this trigger. Immune/inflammatory candidates are particularly attractive in this regard. The results this study may also have therapeutic implications. For example, if alpha-synuclein disaggregating agents achieve therapeutic utility in the coming years, our studies may indicate that such agents may be capable of accessing nigrostriatal axon terminals without requiring pharmaceutical or mechanical disruption of the BBB.
PURPOSE:To obtain a reagent which is stable for a long period of time and is free natural flocculation of latex particles by incorporating >=1 kind from the group consisting of three kinds; gamma-collidine, imidazole (deriv.) and propane 1,3- diol deriv. in an antigen or antibody-sensitized latex. CONSTITUTION:gamma-Collidine (2,2,6-trimethyl pyridine), imidazole or imidazole dervi. expressed by the formula I (R1, R2, R3 and R4 are H, C1-5 alkyl) and the propane 1, 3-diol deriv. expressed by the formula II (R1 is H or C1-5 alkyl) are added in a range of 0.05-2.0w/v% to a latex reagent sensitized with an antigen or antibody at 0.01-5.0w/v% in terms of latex concn. The reagent which is free from natural flocculation and is substantially free from a change in absorbancy when preserved for a long period of time at 4-7 deg.C and can measure the antigen or antibody with good accuracy is thus obtd.
The proliferative and migratory abilities of vascular smooth muscle cells (VSMCs) play a crucial role in neointima formation following vascular injury. Skp2 facilitates proliferation and migration in cells through cell cycle regulation, presenting an important therapeutic target for atherosclerosis, pulmonary hypertension, and vascular restenosis. This study aimed to identify a natural product capable of inhibiting neointima formation post vascular injury. Here, we demonstrate that troxerutin, a flavonoid, significantly reduced viability and downregulated Skp2 in VSMCs. Moreover, troxerutin exhibited anti-proliferative effects on VSMCs and mitigated neointima formation. These findings collectively elucidate the intrinsic mechanism of troxerutin in treating atherosclerosis, pulmonary hypertension, and vascular restenosis by targeting the E3-linked enzyme Skp2.

Alzheimer's disease (AD) that characterized by progressive cognitive decline, memory and behavior impairment, is the most common form of dementia in the elderly. A novel and potentially powerful strategy for AD prevention and treatment is an immunotherapy that via Abeta-specific antibodies could facilitate the clearance of amyloid deposits from the brains of AD patients. Epitope vaccines composed of several copies of self B cell epitope of amyloid peptide, foreign T cell epitope derived from the conventional vaccines or pathogens to which the human population is frequently exposed and molecular adjuvant are the subject of our patent. The rationale to use N>1 copies of B cell epitope in vaccine composition is to significantly enhance the anti-Aß humoral immune response and the avidity of Aß specific antibodies. The rationale to use foreign T cell epitope is to avoid the generation of autoreactive T cells and to overcome tolerance to self-epitope. More importantly, inclusion of various Th epitopes in the composition of the epitope vaccine will allow to induce quick and potent ant-Aß antibody responses using pre-existing memory CD4+Th cells induced in general population by previous infections and/or immunizations with conventional vaccines, for example Tetanus, Diphtheria, Pertussis, Influenza, HBV.
The invention relates to a chimeric virus for expressing porcine reproductive and respiratory syndrome of a G2 type porcine epidemic diarrhea virus S/S1 and application thereof, belonging to the technical field of veterinary biological products. The invention provides two PRRSV chimeric viruses which recombinantly express the G2 type epidemic strain S or S1 gene of PEDV. Both chimeric viruses constructed based on the PRRSV natural attenuated strain infectious cloning platform can induce the pig body to simultaneously produce neutralizing antibodies against PEDV and PRRSV. The chimeric viruses can be used as live vector vaccine candidate strains for developing novel genetic engineering vaccines against epidemic strains of PEDV and PRRSV simultaneously. The invention relates to construction and rescue of two PRRSV chimeric viruses which are used for recombining and expressing G2 type PEDV epidemic strain S or S1 genes. The chimeric viruses provide novel vaccine candidate strains and key technical support for effectively preventing and controlling epidemic situations of PED and PRRS, and meanwhile, successful development of genetic engineering live vaccines for resisting epidemic strains of PEDV and PRRSV can realize 'one-needle two-prevention', and have great economic value and good market prospect.

The patients with bowel dysfunction following low anterior resection performed at least 1 year ago will undergo acupuncture. The acupuncture procedure is performed by one well trained person, 1 time per week in total of 10 weeks on the same day time. Sterile, disposable, stainless steel acupuncture needles (40x0.25 mm diameter) were inserted to corporal acupoints, with initial gentle stimulation by quick rotation of 1080°, after then leaving needle in located place for twenty minutes. Needling deep - 0.5-1 cm. If the intent was to invigorate - the needle was inserted to the flow of energy; if harmonization needed - the needle was placed perpendicular to the point flow of energy; if sedation was needed, needles were placed against to the flow of energy on channel. The selection of acupoints was based according by traditional Chinese medicine, literature findings.
The physical and mental/emotional health of people with autism spectrum disorder (ASD) are closely connected. The emerging data on immune abnormalities and gut microbiome differences, and interactions of the genome with these suggest a possible etiological link between physical and mental dysfunction, especially the gastrointestinal (GI) dysfunction and severe anxiety that many individuals with ASD manifest. The investigators have preliminary clinical evidence that children with ASD \& GI symptoms differ in microbiome composition and function from neurotypical children with GI symptoms. The investigators hypothesize that altered host-microbial signals, which include altered fecal neurotransmitter gamma-aminobutyric acid (GABA) levels contribute towards anxiety and sensory over-responsivity in ASD. Our preliminary findings also show that probiotic Visbiome Extra Strength, improves GI and pain symptoms, correlating with altered gut microbiome composition and related metabolites (the macrobiome). The proposed crossover trial will explore the possibilities of this new appreciation of the microbiome-mental/physical function connection for ASD, GI dysfunction, and anxiety. If altering the gut microbiome results in better GI and emotional function, it could improve the quality of life for children with ASD and their parents. A pilot trial with 12 children with ASD will test feasibility for a proposed three-site crossover randomized clinical trial (RCT) of probiotics (beneficial bacteria including Lactobacilli \& Bifidobacteria) in 60 children 3-12 years old with ASD, GI dysfunction, \& anxiety. In a balanced crossover children will be randomized 1;1 to Visbiome or placebo first, 8 weeks per condition with 3 weeks washout between. The investigators have access to significant fecal microbiome and metabolome data from NIH-funded Human Microbiome Projects (HMP) on similar-age healthy and irritable-bowel children, with and without ASD. These will help leverage our understanding of macrobiome changes that correlate with functional improvement of GI and abdominal pain symptoms. Pilot study efficiency will also benefit from those HMPs having already collected and analyzed baseline stools for some children with ASD, thus saving significant costs for baseline stool analyses for the pilot.

PURPOSE: There are limited data on ablation effects of thulium fiber laser (TFL) settings with varying stone composition. Similarly, little is known surrounding the photothermal effects of TFL lithotripsy regarding the chemical and structural changes after visible char formation. We aim to understand the TFL's ablative efficiency across various stone types and laser settings, while simultaneously investigating the photothermal effects of TFL lithotripsy.
MATERIALS AND METHODS: Human specimens of calcium oxalate monohydrate, calcium oxalate dihydrate, uric acid, struvite, cystine, carbonate apatite, and brushite stones were ablated using 13 prespecified settings with the Coloplast TFL Drive. Pre- and postablation mass, ablation time, and total energy were recorded. Qualitative ablative observations were recorded at 1-minute intervals with photographs and gross description. Samples were analyzed with Fourier-transform infrared spectroscopy pre- and postablation and electron microscopy postablation to assess the photothermal effects of TFL.
RESULTS: Across all settings and stone types, 0.05 J × 1000 Hz was the best numerically efficient ablation setting. When selected for more clinically relevant laser settings (ie, 10-20 W), 0.2 J × 100 Hz, short pulse was the most numerically efficient setting for calcium oxalate dihydrate, cystine, and struvite stones. Calcium oxalate monohydrate ablated with the best numerical efficiency at 0.4 J × 40 Hz, short pulse. Uric acid and carbonate apatite stones ablated with the best numerical efficiency at 0.3 J × 60 Hz, short pulse. Brushite stones ablated with the best numerical efficiency at 0.5 J × 30 Hz, short pulse. Pulse duration impacted ablation effectiveness greatly with 6/8 (75%) of inadequate ablations occurring in medium or long pulse settings. The average percent of mass lost during ablation was 57%; cystine stones averaged the highest percent mass lost at 71%. Charring was observed in 36/91 (40%) specimens. Charring was most often seen in uric acid, cystine, and brushite stones across all laser settings. Electron microscopy of char demonstrated a porous melting effect different to that of brittle fracture. Fourier-transform infrared spectroscopy of brushite char demonstrated a chemical composition change to amorphous calcium phosphate.
CONCLUSIONS: We describe the optimal ablation settings based on stone composition, which may guide urologists towards more stone-specific care when using thulium laser for treating renal stones (lower energy settings would be safer for ureteral stones). For patients with unknown stone composition, lasers can be preset to target common stone types or adjusted based on visual cues. We recommend using short pulse for all TFL lithotripsy of calculi and altering the settings based on visual cues and efficiency to minimize the charring, an effect which can make the stone refractory to further dusting and fragmentation.

Date Dec. 10, 1992This invention relates to ultrasound contrast agents in the form of microparticles comprising a biotolerable matrix (e.g. of a carbohydrate or an X-ray contrast agent) in association with a gas or a precursor therefor. The contrast agents are stabilized to enhance their in vivo stability and/or echogenicity by covalently modifying the structure of the matrix, e.g. to introduce crosslinking groups or to attach lipophilic groups and/or molecules. The covalent moieties may include biodegradable linkages to assist rapid subsequent elimination of the contrast agents from the system.
BACKGROUND: The clinical application of human induced pluripotent stem cell-derived cardiomyocytes (CMs) for cardiac repair commenced with the epicardial delivery of engineered cardiac tissue; however, the feasibility of the direct delivery of human induced pluripotent stem cell-derived CMs into the cardiac muscle layer, which has reportedly induced electrical integration, is unclear because of concerns about poor engraftment of CMs and posttransplant arrhythmias. Thus, in this study, we prepared purified human induced pluripotent stem cell-derived cardiac spheroids (hiPSC-CSs) and investigated whether their direct injection could regenerate infarcted nonhuman primate hearts.
METHODS: We performed 2 separate experiments to explore the appropriate number of human induced pluripotent stem cell-derived CMs. In the first experiment, 10 cynomolgus monkeys were subjected to myocardial infarction 2 weeks before transplantation and were designated as recipients of hiPSC-CSs containing 2×107 CMs or the vehicle. The animals were euthanized 12 weeks after transplantation for histological analysis, and cardiac function and arrhythmia were monitored during the observational period. In the second study, we repeated the equivalent transplantation study using more CMs (6×107 CMs).
RESULTS: Recipients of hiPSC-CSs containing 2×107 CMs showed limited CM grafts and transient increases in fractional shortening compared with those of the vehicle (fractional shortening at 4 weeks after transplantation [mean ± SD]: 26.2±2.1%; 19.3±1.8%; P<0.05), with a low incidence of posttransplant arrhythmia. Transplantation of increased dose of CMs resulted in significantly greater engraftment and long-term contractile benefits (fractional shortening at 12 weeks after transplantation: 22.5±1.0%; 16.6±1.1%; P<0.01, left ventricular ejection fraction at 12 weeks after transplantation: 49.0±1.4%; 36.3±2.9%; P<0.01). The incidence of posttransplant arrhythmia slightly increased in recipients of hiPSC-CSs containing 6×107 CMs.
CONCLUSIONS: We demonstrated that direct injection of hiPSC-CSs restores the contractile functions of injured primate hearts with an acceptable risk of posttransplant arrhythmia. Although the mechanism for the functional benefits is not fully elucidated, these findings provide a strong rationale for conducting clinical trials using the equivalent CM products.
The study was planned and conducted as a randomized controlled experiment. The sample of the randomized controlled trial consisted of 70 patients who applied to the emergency department with a migraine attack and met the study criteria. Data were collected via Patient Information Form, 24-Hour Migraine Quality of Life Scale, Visual Analogue Scale, Sphygmomanometer, and Pulse oximeter. Along with the medical treatment, patients of experimental group were massaged for 15 minutes with an aromatic oil mixture (lavender and peppermint) applied on the temple and root of the neck, and this application continued for three weeks. Control group patients, however, received only medical treatment. Descriptive statistics methods, Shapiro Wilks test, Wilcoxon Signed Ranks Test, Mann Whitney U Test, Kruskal Wallis Test, Fisher's Exact Test and Chi-Square Test were used for data evaluation.
Subjects in this arm will perform pelvic floor muscle exercises (Kegels) for the treatment of stress or mixed urinary incontinence. Subjects will be asked to perform exercises three times daily for 8 weeks. At the beginning of the study, four weeks later, and eight weeks later, subjects will undergo pelvic floor muscle testing (using the PFDx device) and surveys to document response to training. After eight weeks, subjects may pursue any additional treatments they wish, but may continue to use the device.
A randomized experimental controlled trial will be carried out to compare the effectiveness of core stabilization exercises performed with and without jaw movements in the management of nonspecific chronic low back pain. A total of 80 male and female volunteers having subjects with chronic nonspecific low back pain will be recruited in this study. All subjects will be assessed for transverse abdominal muscle strength contraction, pain and disability using Pressure Biofeedback Unit (BPU), Numeric Pain Rating Scale (NPRS 0-10cm) and Ronald Morris Disability Questionnaire (RMDQ 0-24) respectively. The scores on the mentioned scales will be documented as per guidelines. After baseline assessment, all subjects will be allocated to two groups through computer-generated random sampling. Group 1 will perform core stability exercises alone; Group 2 will perform core stability exercises with teeth clenching This study will be conducted at the Physiotherapy Department of Sindh Institute of Physical Medicine and Rehabilitation (SIPM\&R). The computer-generated random sampling technique will be used to allocate the participants into the study groups. Data will be analyzed using SPSS 22 and one-way repeated measure ANOVA will be applied to see the mean difference in the 2 groups. For pair-wise comparison, the Tukey test will be applied. For pain and disability scales Friedman's test will be applied to see the two scales' median differences.
