  • Rockwool substrate has superior physicochemical characteristics and is often used in crop cultivation. However, rockwool substrate has the disadvantages of high purchase cost and difficulty in disposal. Reuse of substrate can compensate for these disadvantages. Substrate must be disinfected and rehydrated during reuse, and various physicochemical changes during this process must also be considered. This study was to compare the physical properties of two types of rockwool substrates (reused and unused) and to evaluate the reuse potential of rockwool substrate by analyzing the chemical properties of the reused rockwool substrate during the rehydration process. The experiment on substrate physicochemical properties comparison was conducted from March to August 2023 using used rockwool substrates in tomato cultivation and unused rockwool substrates. Drainage time, drainage volume, and substrate weight were measured using load cells installed at the top and bottom of the irrigation monitoring system. The reused rockwool substrate weight and density were higher than those of the unused rockwool substrate, while the average drainage time after irrigation was 1.5 times longer for the reused rockwool than for the unused rockwool. The salinity concentration in different parts of the reused rockwool substrate was found to be lower in the reused rockwool substrate compared to the unused rockwool substrate. The electrical conductivity of the drainage was at its peak at the beginning of the drainage and decreased exponentially as the drainage volume increased. Change in electrical conductivity of the drainage over the irrigation time showed an exponential decay pattern. Through the experiments, the potential reusability of the rock wool substrate was assessed by conducting a comparative analysis of its physicochemical properties.

  • In this study, the growth, physical characteristics of fruit and soil chemistry were investigated by grouping S. thea populations. The soil for each group was sandy loam or sandy loam, and it was analyzed to be slightly acidic to neutral, with a pH ranging from 5.6 to 7.0. Additionally, the leaf size was highest in the G7 group, and overall fruit growth was highest in the G1 group, confirming differences between the groups. The sweetness ranged from 16.8° Brix to 12.3° Brix, indicating a higher sweetness compared to Vaccinium oldhamill, blueberry, and blackberry. The correlation analysis between soil chemistry and S. thea growth characteristics revealed a significant negative correlation between calcium (Ca) and fruit growth characteristics. Furthermore, a significant positive correlation was observed between sodium (Na) and fruit acidity, as well as between cation exchange capacity (CEC) and fruit hardness.

  • This study was conducted to investigate the effect of the mating system on the retail cut yield and meat quality in pigs. A total of 210 samples were used to estimate meat productivity and meat quality two blocks of two boarlines Duroc (D) and Berkshire (B) were mated to sows of the sowlines Yorkshire×Landrace (YL) and Berkshire (B). Results showed that YLD (YL♀×D♂) and BD (B♀×D♂) had higher percentages of Boston butt and belly than YLB while it has higher percentages of lean meat yield than YLB (YL♀×B♂). There were no significant differences in crude protein and ash content of pork from different breeds (P>0.05). However, YLB and YLD had higher moisture content in loin and Boston butt than BD (P<0.05). The pH of BD was highest in pork loin and belly (P<0.05). There differences in meat yield, pH and moisture content among the genotypes suggested that pork quality might be affected by the lightness and cooking loss. BD was lowest lightness value (CIE L*) and cooking loss in pork loin among the genotypes (P<0.05). The percentage of saturated palmitic acid (C16:0) in Boston butt (P<0.05) of BD had significant lower, while the percentage of unsaturated palmitoleic (C16:1) and oleic acid (C18:1) had higher in pork loin and belly (P<0.05). Drip and marbling score were found significantly different in genotypes and BD had lower drip and higher marbling score in pork loin and belly (P<0.05). The sensory evaluations indicated that the highest overall acceptability in BD was attained. From the results, BD breed had highest meat quality among crossbred pigs.

  • Plant viruses of tobacco including tobacco mosaic virus (TMV) and potato virus Y (PVY) cause severe economic losses in leaf-tobacco production. Cultural practices do not provide sufficient control against the viruses. Use of valuable resistant cultivars is most recommendable for the control of the viruses. However, conventional breeding programs are not always proper for the development of virus-resistant plants mostly owing to the frequent lack of genetic sources and introduction of their unwanted properties. Therefore, we tried to develop virus-resistant tobacco plants by transforming commercial tobacco cultivars, NC 82 and Burley 21, with coat protein (CP) or replicase (Nlb) genes of TMV and PVY necrosis strain (PVY-VN) with or without untranslated region (UTR) and with or without mutation. Each cDNA was cloned and inserted in plant expression vectors with 1 or 2 CaMV 35S promotors, and introduced into tobacco leaf tissues by Agrobacterium tumefaciens LBA 4404. Plants were regenerated in kanamycin-containing MS media. Regenerated plants were tested for resistance to TMV and PVY In these studies, we could obtain a TMV-resistant transgenic line transformed with TMV CP and 6 genetic lines with PVY-VN cDNAs out of 8 CP and replicase genes. In this presentation, resistance rates, verification of gene introduction in resistant plants, stability of resistance through generations, characteristics of viral multiplication and translocation in resistant plants, and resistance responses relative to inoculum potential and to various PVY strains will be shown. Yield and quality of leaf tobacco of a promising resistant tobacco line will be presented.

  • Malignant small round cell tumor (SRCT) of the thoracopulmonary region appears to originate in the soft tissues of the chest wall or the peripheral lung. A differential diagnosis of poorly differentiated small round cell tumors which include Ewing's sarcoma of bone and soft tissue, embryonal rhabdomyosarcoma, Askin tumor, neuroblastoma, peripheral neuroectodermal tumor, small cell osteogenic sarcoma and Iymphoma are often difficult by light microscopy alone. In recent, by the extensive studies electron microscopic examination, histochemical study, immune-chemical study, cytogenetics and gene analysis, these tumors may be derived from the primitive and pluripotential cells, differentiating into mesenchymal, epithelial and neural features in variable proportions. Treatment for SRCT of thoracopulmonary region is not determined because of massive involvement of the lung, pleura or soft tissues of the chest wall resulted in a dismal outcome despite aggressive surgery, irradiation and chemotherapy.

  • Rothmund-Thomson syndrome (RTS), is a rare autosomal recessive disorder, characterized by : skin photosensitivity, poikiloderma, sparse hair, sparse eyebrows/lashes, short stature, skeletal abnormalities, cataracts, and an increased risk of malignancy. Skeletal abnormalities include : dysplasia, absent or malformed bones, such as absent radii, osteopenia, and delayed bone formation. RTS is thought to result from chromosomal instability, and children with RTS are at risk of cancer. Reported cancers in children with RTS include : basal cell carcinoma, squamous cell carcinoma of the skin and osteosarcoma of bone. We report an 11 year-old boy, who presented to our institution with poikilodermatous skin change with telangiectasia and hyperpigmentation, absence of radius and thumb, and the development of osteosarcoma of the left tibia. The patient is now receiving supportive care and is receiving maintenance chemotherapy after surgery for osteosarcoma.

  • Sarcoidosis is a multi-systemic granulomatous disorder of unknown etiology. The characteristic pathological finding is the presence of non-caseating granulomas. The lungs are primarily affected, however other organs may be involved causing various symptoms and ambiguous laboratory findings can be present. There are a few reported cases of sarcoidosis with elevated tumor markers. We describe a 68-year-old woman presenting with sarcoidosis showing elevated serum carcinoembryonic antigen (CEA). The possibility of cancer arising from serum CEA such as gastrointestinal cancer, breast cancer and lung cancer was excluded. A transbronchial lung biopsy demonstrated a non-caseating granuloma without necrosis. As a result prescribed 30 mg prednisolone daily to the patient and serum CEA was decreased after 1 month of treatment. We report a case of pulmonary sarcoidosis with elevated serum CEA.
