Leaves are the final site of salinity perception through the roots. To better understand how wheat chloroplasts proteins respond to salt stress, the study aimed to the physiochemical and comparative proteomics analysis. Seedlings (12-days-old) were exposed to 150 mM NaCl for 1, 2, or 3 days. Na(+) ions were rapid and excessively increase in roots, stems and leaves. Photosynthesis and transpiration rate, stomatal conductance, and relative water content decreased whereas the level of proline increased. Statistically significant positive correlations were found among the content of hydrogen peroxide, activity of catalase, and superoxide dismutase under salt stress in wheat. Protein abundance within the chloroplasts was examined by two-dimensional electrophoresis. More than 100 protein spots were reproducibly detected on each gel, 21 protein spots were differentially expressed during salt treatment. Using linear quadruple trap-Fourier transform ion cyclotron resonance (LTQ-FTICR) hybrid mass spectrometry, 65 unique proteins assigned in the differentially abundant spots. Most proteins were up-regulated at 2 and 3 days after being down-regulated at 1 day. Others showed only slight responses after 3 days of treatment, including Rubisco, glutamate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase, isocitrate dehydrogenase, photosystem I, and pyridoxal biosynthesis protein PDX1.2 and PDX1.3. The ATP synthase (α, β, and γ) and V-type proton ATPase subunits were down-regulated resulting showed negative impact by Na(+) on the photosynthetic machinery. This ephemeral increase and subsequent decrease in protein contents may demonstrate a counterbalancing influence of identified proteins. Several proteins such as cytochrome b6-f (Cyt b6-f), germin-like-protein, the γ-subunit of ATP synthase, glutamine synthetase, fructose-bisphosphate aldolase, S-adenosylmethionine synthase, carbonic anhydrase were gradually up-regulated during the period of treatment, which can be identified as marker proteins.

The prevalence of intervertebral disc herniation (IDH) of the thoracic spine is rare compared to the cervical or lumbar spine. In particular, IDH of the upper thoracic spine is extremely rare. We report the case of T1-2 IDH and its treatment, with a literature review. A 37-year-old male patient visited our hospital due to radiating pain at the left upper extremity and weakness of grip power. In cervical spine magnetic resonance images, T1-2 disc space showed herniated disc material and compressed T1 root was identified. Laminoforaminotomy was performed with a posterior approach. The radiating pain and weakness of grip power improved immediately after the surgery. Of patients who show radiating pain or numbness at the medial aspect of forearm, or weakness of intrinsic muscle of hand, can be suspected to have T1 radiculopathy. A detailed physical examination and a radiologic evaluation including this area should be required for the T1 radiculopathy.

Children with autism are often medicated to manage emotional and behavioral symptoms; yet, data on such pharmacotherapy is insufficient. In this study, we investigated the Korean National Health Insurance Claims Database (NHICD) information related to autism incidence and psychotropic medication use. From the 2010–2012 NHICD, we selected a total of 31,919,732 subjects under 19 years old. To examine the diagnostic incidence, we selected patients who had at least one medical claim containing an 10th revision of International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for pervasive developmental disorder, F84, not diagnosed in the previous 360 days. Psychotropics were categorized into seven classes. Then, we analyzed the data to determine the mean annual diagnostic incidence and psychotropic prescription trends. Diagnostic incidence was 17,606 for the 3 years, with a mean annual incidence per 10,000 population of 5.52. Among them, 5,348 patients were prescribed psychotropics. Atypical antipsychotics were the most commonly used, followed by antidepressants. An older age, male sex, and the availability of medical aid were associated with a higher rate of prescription than observed for a younger age, female sex, and the availability of health insurance. Psychotropic drugs were used for less than one-third of patients newly diagnosed with autism, and prescription differed by sex and age. Increased diagnostic incidence is associated with an increased prescription of psychotropic drugs. Therefore, medication-related safety data and policies for psychotropic drugs in autism should be prepared.

Objective We aimed to investigate the current diagnostic incidence, and medical and psychiatric comorbidities of reactive attachment disorder (RAD) using the National Health Insurance Review and Assessment (HIRA) claims data. Methods To examine the diagnostic incidence, we selected patients who were under 10-year-old and who had at least one medical claim containing a 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for RAD (F94.1 and F94.2) and who had not been diagnosed in the previous 360 days, from 2010 to 2012. In this study, we used the term ‘reactive attachment disorder’ representing for both RAD per se and Disinhibited social engagement disorder. Comorbid disorders were categorized according to ICD-10. Results Among 14,029,571, the total population under 10-year-old during 2010–2012, incident cases of RAD were 736. The mean diagnostic incidence of RAD was 5.25 per 100,000 annually. Language disorders (F80-84) were the most common psychiatric comorbidities in both boys and girls in age groups 0–3 years and 4–6 years, and attention deficit hyperactivity disorder was the most common in both sex aged 7–9 years. In non-psychiatric comorbidities, diseases of the respiratory system (J00–99) were the commonest in both sex in all age groups, and diseases of the digestive system (K00–99) were the next. Conclusion RAD was very rare in practice and would be disguised as other psychiatric disorders. Children with RAD might have more medical comorbidities than typically developed children.
