This study aimed to inhibit Escherichia coli (E. coli) O157:H7 artificially contaminated in fresh meat using bacteriophage. Among 14 bacteriophages, the highly lytic bacteriophage BPECO19 strain was selected to inhibit E. coli O157:H7 in artificially contaminated meat samples. Bacteriophage BPECO19 significantly reduced E. coli O157:H7 bacterial load in vitro in a multiplicity of infection (MOI)-dependent manner. E. coli O157:H7 was completely inhibited only in 10 min in vitro by the treatment of 10,000 MOI BPECO19. The treatment of BPECO19 at 100,000 MOI completely reduced 5 Log CFU/cm<sup>2</sup> E. coli O157:H7 bacterial load in beef and pork at 4 and 8h, respectively. In chicken meat, a 4.65 log reduction of E. coli O157:H7 was observed at 4 h by 100,000 MOI. The treatment of single bacteriophage BPECO19 was an effective method to control E. coli O157:H7 in meat samples.

Immunoglobulin G4-related disease (IgG4-RD) is an autoimmune disorder associated with fibroinflammatory conditions that can affect multiple organs. Hallmark histopathological findings of IgG4-RD include lymphocytic infiltration of IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. However, little is known about central nervous system involvement of IgG4-RD. Hypertrophic pachymeningitis (HP) has recently been reported as a manifestation of IgG4-RD, which may have previously been demonstrated in a significant percentage of idiopathic cases. Herein, we report a rare case of a 63-year-old male who presented with a scalp mass that mimicked a brain tumor. He was diagnosed with IgG4-related HP (IgG4-RP) after surgery. This case suggests that awareness of a possibility of IgG4-RP in patients with isolated scalp masses, even in the absence of systemic symptoms, is crucial. A combination of careful history taking, evaluation of serum IgG4-levels and imaging as an initial work-up, followed by tissue biopsy, is important for the differential diagnosis of IgG4-RP, malignancy, and other infectious diseases.

Objective: This study aimed to identify the effects of performing shoulder and hip abduction during the V-sit exercise on abdominal muscle activity. Design: Cross-sectional study. Methods: Thirty healthy adults volunteered for this experiment. The participants randomly performed 6 types of V-sit exercises, including V-sit alone (hip 0°, shoulder 0°), V-sit with hip abduction 0° and shoulder abduction 15°, V-sit with hip abduction 0° and shoulder abduction 30°, V-sit with hip abduction 15° and shoulder abduction 0°, V-sit with shoulder and hip abduction 15°, and V-sit with shoulder abduction 30° and hip abduction 15°. EMG data were recorded from the rectus abdominis (RA), external oblique (EO), and internal oblique (IO) muscles of both sides. All abdominal EMG data during the six types of V-sit exercises were measured for 5 seconds, three times, and recorded for the middle 3 seconds excluding the 1 second at the start and end. Results: V-sit with shoulder abduction 30° resulted in significantly greater muscle activity of both RA, EO compared to shoulder abduction 0°, shoulder abduction 15° (p<0.05) and V-sit with shoulder abduction 15° showed significantly greater muscle activation of the RA compared with shoulder abduction 0° (p<0.05). The muscle activity of both EO and IO in the V-sit with hip abduction 15° was significantly greater than hip abduction 0° in all shoulder conditions (p<0.05). Conclusions: Greater angles of shoulder and hip abduction produced more abdominal muscle activity increases during the V-sit exercises. Shoulder abduction affected the RA, EO muscle activation and hip abduction affected the EO, IO muscle activation. This study showed that shoulder and hip abduction during V-sit exercises enabled effective activation of the trunk muscles.
