Abstract
The cytoplasmic RIG-I-like receptors (RLRs) recognize viral RNA and initiate innate antiviral immunity. RLR signaling also triggers glycolytic reprogramming through glucose transporters (GLUTs), whose role in antiviral immunity is elusive. Here, we unveil that insulin-responsive GLUT4 inhibits RLR signaling independently of glucose uptake in adipose and muscle tissues. At steady state, GLUT4 is docked at the Golgi matrix by ubiquitin regulatory X domain 9 (UBXN9, TUG). Following RNA virus infection, GLUT4 is released and translocated to the cell surface where it spatially segregates a significant pool of cytosolic RLRs, preventing them from activating IFN-β responses. UBXN9 deletion prompts constitutive GLUT4 trafficking, sequestration of RLRs, and attenuation of antiviral immunity, whereas GLUT4 deletion heightens RLR signaling. Notably, reduced GLUT4 expression is uniquely associated with human inflammatory myopathies characterized by hyperactive interferon responses. Overall, our results demonstrate a noncanonical UBXN9-GLUT4 axis that controls antiviral immunity via plasma membrane tethering of cytosolic RLRs.

Abstract
Introduction:
The adaptive metabolic regulation of glucose and fatty acid in the heart plays a critical role in limiting cardiac damage caused by ischemia and reperfusion (I/R). TUG (tether containing a UBX domain, for GLUT4) can be cleaved to mobilize glucose transporter GLUT4 from intracellular vesicles to the cell surface in skeletal muscle and adipose in response to insulin stimulation. The energy sensor AMP-activated protein kinase (AMPK) plays an important cardioprotective role in response to ischemic insults by modulating GLUT4 translocation.
Hypothesis:
TUG is one of the downstream targets of AMPK in the heart. TUG could be phosphorylated by ischemic AMPK and cleaved to dissociate with GLUT4 and increase GLUT4 translocation in the ischemic heart.
Methods:
In vivo
regional ischemia by ligation of left anterior coronary artery and
ex vivo
isolated mouse heart perfusion Langendorff system were used to test the hypothesis.
Results:
Antithrombin (AT) is an endogenous AMPK agonist in the heart and used to define the role of TUG in regulating GLUT4 trafficking during ischemia and reperfusion in the heart. AT showed its cardioprotective function through recovering cardiac pumping function and activating AMPK. The results showed that AMPK activation by AT treatment was through LKB1 and Sesn2 complex. Furthermore, the
ex vivo
heart perfusion data demonstrated that AT administration significantly increase GLUT4 translocation, glucose uptake, glycolysis and glucose oxidation during ischemia and reperfusion (p<0.05
vs
. vehicle). Moreover, AT treatment increased abundance of a TUG cleavage product (42 KD) in response to I/R. The TUG protein was clearly phosphorylated by activated AMPK in HL-1 cardiomyocytes. The
in vivo
myocardial ischemia results demonstrated that ischemic AMPK activation triggers TUG cleavage and significantly increases GLUT4 translocation to the cell surface. Moreover, an augmented interaction between AMPK and TUG was observed during ischemia.
Conclusions:
Cardiac AMPK activation stimulates TUG cleavage and causes the dissociation between TUG and GLUT4 in the intracellular vesicles. TUG is a critical mediator that modulates cardiac GLUT4 translocation to cell surface and enhances glucose uptake by AMPK signaling pathway.

Abstract
Duchenne muscular dystrophy (DMD) is the most common and lethal genetic muscle disorder lacking a curative treatment. We wish to use the dystrophin-deficient golden retriever muscular dystrophy (GRMD) dog, a canine model of DMD, to investigate adeno-associated virus (AAV) vector-mediated minidystrophin gene therapy. The dog model is useful in evaluating vector dose requirement and immunological consequences owing to its large size and outbred nature. In this study, we have cloned and constructed a canine minidystrophin gene vector. Owing to limited availability of the GRMD dogs, here we first examined the functions and therapeutic effects of the canine minidystrophin in the mdx mouse model. We observed efficient minigene expression without cellular immune responses in mdx mice after AAV1-cMinidys vector intramuscular injection. We also observed restoration of the missing dystrophin-associated protein complex (DPC) onto the sarcolemma, including sarcoglycans and dystrobrevin, and a partial restoration of alpha-syntrophin and neural nitric oxide synthase (nNOS). In addition, minidystrophin treatment ameliorated dystrophic pathology, such as fibrosis and myofiber central nucleation (CN). CN remained minimal (<2%) after AAV injection in the neonatal mdx mice and was reduced from more than 75% to about 25% after AAV injection in adult mdx mice. Finally, in vivo cell membrane leakage test with Evans blue dye showed that the canine minidystrophin could effectively protect the myofiber plasma membrane integrity. Our results, thus, demonstrated the functionality and therapeutic potential of the canine minidystrophin and paved its way for further testing in the GRMD dog model.

Abstract
Deteriorating water treatment facilities and distribution systems pose a significant public health threat, particularly in republics of the former Soviet Union. Interventions to decrease the disease burden associated with these water systems range from upgrading distribution networks to installing reverse osmosis technology. To provide insight into this decision process, we conducted a randomized intervention study to provide epidemiologic data for water policy decisions in Nukus, Uzbekistan, where drinking water quality is suboptimal. We interviewed residents of 240 households, 120 with and 120 without access to municipal piped water. Residents of 62 households without piped water were trained to chlorinate their drinking water at home in a narrow-necked water container with a spout. All study subjects (1583 individuals) were monitored biweekly for self-reported diarrheal illness over a period of 9.5 weeks. The home chlorination intervention group had the lowest diarrheal rate (28.8/1,000 subjects/month) despite lack of access to piped water in their homes. Compared with the two groups that did not receive the intervention this rate was one-sixth that of the group with no piped water (179.2/1,000 subjects/month) and one-third that of the households with piped water (75.5/1,000 subjects/month). More than 30% of the households with piped water lacked detectable levels of chlorine residues in their drinking water, despite two-stage chlorination of the source water, and were at increased risk of diarrhea. Forty-two percent of these municipal users reported that water pressure had been intermittent within the previous two days. The dramatic reduction in diarrheal rates in the home-chlorination intervention group indicates that a large proportion of diarrheal diseases in Nukus are water-borne. The home-chlorination group had less diarrhea than the group with piped water, implicating the distribution system as a source of disease transmission. Taken together, these epidemiologic data would support the hypothesis that diarrhea in the piped water group could be attributed to cross-contamination between the municipal water supply and sewer, due to leaky pipes and lack of water pressure. Relatively inexpensive steps, including chlorination, maintaining water pressure, and properly maintaining the distribution system, rather than reverse osmosis technology, should reduce diarrheal rates.

Abstract
Ewes synchronised with progestin impregnated sponges to reduce the spread of lambing were treated during the periparturient period with anthelmintic. The suppression of nematode egg output in faeces was measured in ewes given ivermectin either by subcutaneous injection or orally, or oxfendazole or levamisole orally. Ivermectin and oxfendazole reduced the output of eggs in the faeces of the ewes significantly (P less than 0.05) and the period of suppressed egg output was extended when ivermectin was given by subcutaneous injection. Plasma pepsinogen activity was estimated as a measure of abomasal damage. Pepsinogen values were significantly (P less than 0.001) lower in those animals treated with ivermectin by subcutaneous injection than in control animals. Levamisole showed a poorer response in terms of the output of eggs in faeces than either ivermectin or oxfendazole.

Abstract
In goats, there was a linear correlation of area under the plasma concentration-time curve (AUC) with dose in the range 0-20 mg/kg as single dosages of oxfendazole (OFZ). The bioavailability of OFZ after oral administration was lower in goats than in sheep. The repetition of three administrations at 24 h intervals produced significant increase in the AUC in comparison with a single administration equivalent to the total dosage (1 X 5.0 and 3 X 1.7 mg/kg). Infection with O. circumcincta produced a 33% decrease in the bioavailability of OFZ.

Abstract
Thirty-two patients with cysts caused by Echinococcus granulosus were treated with albendazole in a dosage of 10 mg/kg/day. Reversible abnormalities in liver-cell function tests were seen in five patients. Some radiological evidence of remission (on serial computed tomographic or ultrasound scanning) was seen in 15 of 22 patients undergoing a therapeutic course of albendazole (as opposed to those treated before or after surgery). In five patients, the cysts virtually disappeared. Apart from reduction in size, the appearance of a halo around the cysts and the apparent disappearance of daughter cysts has been seen. Serological findings have not correlated well with radiological or clinical improvement. Serum and cyst concentrations of albendazole sulfoxide (the principal metabolite) have been measured.
