Regression analyses indicated that ratings of aggressive responses were more strongly related to aggressive intentions, and ratings of effective responses were more strongly related to intentions to use effective responses. Adolescents who varied in their level of aggression differed in their ratings of aggressive and nonviolent responses. Those reporting higher levels of aggression showed less differentiation between effective and ineffective nonviolent responses compared with those reporting lower levels.
These findings underscore the need for further efforts to identify factors that promote effective nonviolent behavior versus those that support aggression. They have important implications for the development of violence prevention programs.

Qualitative and quantitative contributions of these sources to ambient PM2.5 (particulate matter with an aerodynamic equivalent diameter below 2.5 µm) concentrations remains uncertain. Stable nitrogen isotopic composition (δ15N) of NH3 and NH4 + (δ15N(NH3) and δ15N(NH4 +), respectively) can yield valuable information about its sources and associated processes. This review provides an overview of the recent progress in analytical techniques for δ15N(NH3) and δ15N(NH4 +) measurement, sampling of atmospheric NH3 and NH4 + in the ambient air and their sources signature (e.g., agricultural vs. fossil fuel), and isotope-based source apportionment of NH3 in urban atmosphere. This study highlights that collecting sample that are fully representative of emission sources remains a challenge in fingerprinting δ15N(NH3) values of NH3 emission sources. Furthermore, isotopic fractionatioementary material includes supplementary tables on summary of recent isotope-based source apportionment studies on ambient NH
derived from δ
N(NH
) values (Table A1); and summary of recent isotope-based source apportionment studies on particulate NH
derived from δ
N(NH
) values (Table A2).

For surface water, the average concentrations of five antibiotic classes decreased in the order sulfonamides (117.9 ng/L) > β-lactams (31.28 ng/L) > quinolones (20.19 ng/L) > macrolides (17.74 ng/L) > trimethoprim (8.93 ng/L). While the highest concentration of SMX was detected at 806.5 ng/L in surface water, those obtained in sediment were only at 1.35 ng/g because of their high solubility in water. Quinolones were found at a maximal concentration of 158.7 ng/L for OFL in water phase whereas those in sediment phase were 4,017 ng/g due to their great affinity in sediment. These findings revealed the different fate and release mechanisms of each antibiotic group in the environment. The ecological risk assessment implied some targeted compounds, and in particular, OFL and AZM could pose high risks to algae in the aquatic ecosystem.Spontaneous resolution of cystic adventitial disease (CAD) is rare with occasional reports in the literature. In this case report, we are describing a 30-year-old man who presented with rapid onset of severe intermittent claudication and was diagnosed with CAD. Resection of the lesion with autologous vein replacement was scheduled. However, the claudication suddenly improved at 4 weeks after onset. Ultrasonography and computed tomography revealed regression of the cystic lesions with resolution of the popliteal artery stenosis. His symptoms did not recur during the 12-month follow-up period. Although it is unclear whether this resolution is permanent, in this report, we describe our experience with a case of CAD that eventually spontaneously regressed and the possibility of conservative treatment.Recurrent varices after surgery (REVAS) is a common problem with no established treatment. Ultrasonography is a hard method to identify the source of veins that cause REVAS, especially in obese patients with thick thighs. Here, we report the case of a 64-year-old obese patient who previously underwent endothermal venous ablation for her right great saphenous vein. The patient presented with right leg swelling and venous ulceration due to REVAS. Although the source of REVAS was unclear because the patient had thick thighs on ultrasonography assessment, venography revealed that the source of REVAS was the incompetent perforator vein (IPV). Selective ablation for the IPV with radiofrequency ablation catheter was performed. We could ablate the target veins selectively so as not to ablate within the deep vein. The patient remains asymptomatic for 2 years after the procedure, and there has been no recurrence of her varicose veins. Venography allows better visualization of the source of REVAS than ultrasonography. With selective ablation, it is especially effective procedure in obese patients, in whom it is difficult to identify and access the source of REVAS with ultrasonography.Pyoderma gangrenosum is an uncommon inflammatory disorder characterized by neutrophilic infiltration of the skin. It can present as skin papules or pustules that progress into painful ulcers. 30-40% of the cases are associated with other systemic diseases such as inflammatory bowel diseases, rheumatoid arthritis, and proliferative hematological disorders. Uniquely, this condition has been associated with systemic lupus erythematosus (SLE). The rarity of this disorder poses a diagnostic and therapeutic challenge. We present a case of a 55-year-old female with a history of SLE and chronic right leg ulcer, presented with increased pain from the ulcer associated with a mild flare of her cutaneous lupus; examination revealed circumferential skin ulcer measuring about 25 cm extending around the right leg above the ankle with prominent fibrinous material and surrounding erythema. Blood work showed elevated WBC with neutrophilic predominance. Serology revealed a positive ANA, elevated RNP, smith, and SSA/Ro antibodies with normal anti-CCP level. Skin biopsy was taken, and it showed a diffuse neutrophilic and lymphocytic infiltrate consistent with the diagnosis of pyoderma gangrenosum. The patient was then treated with topical and systemic steroids and sequentially with dapsone, methotrexate, mycophenolate, and cyclosporine for over a two-year period but failed to show any improvement. Therefore, a trial of intravenous immunoglobulin (IVIG) therapy was attempted and produced a dramatic response after two-month infusions characterized by shrinking in the size of the ulcer and resolving pain. We believe that refractory PG poses a therapeutic challenge, and despite a lack of specific guidelines, IVIG can be attempted if initial suppressive treatment fails to show signs of improvement.Syncope is common in the pediatric population and occurs in up to 15 percent of children prior to the end of adolescence. AD80 While the etiology of syncope in children is often benign and the majority of cases can be explained by isolated changes in vasomotor tone, a thorough evaluation is warranted to rule out more serious, life-threatening causes of syncope. Here, we present three atypical cases of syncope a young judo player with recurrent syncope and dizziness, a teenage boy with syncopal episodes always preceded by stretching, and a child who experienced urticaria before losing consciousness. Herein, we review the pathophysiology, diagnosis, and management of syncope in children and adolescents.We report a case of an incidental positron emission tomography avid right middle lobe lesion which was increasing in size. Due to concerns regarding malignancy, the patient underwent right middle lobectomy. Microscopic examination showed a 12 × 10 × 10 mm poorly circumscribed lesion composed of eosinophilic material. The material labelled strongly for kappa light chains; however, Congo red stain was only weakly positive and without "apple-green" positive birefringence under polarised light. Electron microscopy revealed fibrillar amyloid-like material. The features were those of kappa light-chain deposition.The induced membrane technique was initially described by Masquelet et al. in 1986 as a treatment for tibia nonunion; then, it became one of the established methods in the management of bone defects. Several changes have been made to this technique and have been used in different contexts and different methodologies. We present the case of a 16-year-old girl admitted to our department for a polytrauma after a motorcycle accident. She presented a Gustilo III-A open fracture of the right femoral shaft with a large bone defect of 8 centimeters that we treated with a modified Masquelet technique. In the first stage, an Open Reduction and Internal Fixation of the fracture was made using a 4,5 mm Dynamic Compression Plate and a PMMA cement was inserted at the bone defect area. The second stage was done after 11 weeks, and the defect area was filled exclusively with bone allograft from a bone bank. Complete bony union was seen at 60 weeks of follow-up. After the removal of the implants by another surgeon, the patien, so additional research and large studies are necessary before giving recommendations.With improving prognosis for recipients of liver transplantation, the necessity of medical care for musculoskeletal disorders, including spinal diseases, of these patients is also increasing. Only a few reports are available on cases of spine surgery following liver transplantation. Furthermore, a case of lateral access surgery following liver transplantation has not thus far been reported. The purpose of this study is to present the first two cases of patients treated with lateral access spine surgery following liver transplantation. Case 1. A 49-year-old female had received living donor liver transplantation (LT) for acute-on-chronic liver failure (ACLF) ten years prior to spine surgery. The patient underwent two levels of lateral lumbar interbody fusion (LLIF) followed by posterior lumbar interbody fusion (PLIF) for degenerative lumbar disease. Although neurological symptoms in the lower extremity improved, a liver disorder resulting from acetaminophen-induced hepatotoxicity occurred at an early stage following spine surgery.
