Estimating production costs and retail prices in different poultry housing systems: conventional, enriched cage, aviary, and barn in Japan.

For many producers, introduction of improved animal welfare systems is a turning point in their future production strategies as it increases production costs. The increase in egg retail prices is of growing concern not only for producers, but also for retailers and consumers. However, no report has calculated the estimated production costs or retail prices associated with introducing practices that support improved animal welfare in poultry farms in Japan. Therefore, this study aimed to estimate the production costs and table egg prices of 6 types of laying hen systems: conventional cage (CC): 8- and 12-tiers (CC8, CC12), enriched cage (EC): 8- and 12-tiers (EC8, EC12), aviary (AV), and barn systems (BR). Production costs include land purchases, construction costs of facilities, equipment and machinery, quantity of feed provided, farming materials invested, and wages. As a result, farm gate prices were estimated as CC8 = 12.19, CC12 = 12.19, EC8 = 14.52, EC12 = 14.52, AV = 21.14, and BR = 28.74 [yen/egg], and the production cost, including building the new farm, increased by EC8 = 19.1%, EC12 = 19.1%, AV = 73.4%, and BR = 135.7%, respectively, referring to the value of CC. The results show that the prices increase in systems between CC and BN. The retail price or table egg price was estimated to be CC8 = 24.68, CC12 = 24.68, EC8 = 28.07, EC12 = 28.07, AV = 37.27, and BR = 48.53 [yen/egg]. The retail price of BR is approximately twice that of CC. In addition, assuming that all of Japan's eggs were produced in the BR system, the soaring cost of eggs would likely affect the prices of factory eggs, such as liquid eggs and other products, thus affecting the prices of various food products. Understanding the significant management costs that affect the retail price of eggs would facilitate improved policies and practical approaches to support poultry farms and sustainable farming activities while addressing public concerns.

A Combined Assessment Method of Phase Angle and Skeletal Muscle Index to Better Predict Functional Recovery after Acute Stroke.

OBJECTIVES: We aimed to investigate whether combination assessment of phase angle (PhA) and skeletal muscle index (SMI), was a possible predictor of physical function at discharge from the hospital in patients with acute stroke. RESEARCH METHODS AND PROCEDURES: In this retrospective cohort study that was conducted from May 2020 and July 2021, we determined PhA and SMI using bioimpedance analysis (BIA) in patients with acute stroke. Patients were classified as normal, low PhA + SMI group, pre-sarcopenia (low SMI only), and dynapenia (low PhA only) using cut-off points (men: SMI < 7.0 kg/m2, PhA < 4.05 degrees; women: SMI < 5.7 kg/m2, PhA < 3.55 degrees). The main outcome was physical function based on functional independence measure motor (FIM-motor) score at discharge. Multiple regression analysis was used to determine the association between low PhA + SMI and FIM-motor score. RESULTS: We included 244 patients (161 men; mean age, 73.9 years). low PhA + SMI was found in 21 (8.6%) patients. Multiple regression analysis showed that low PhA + SMI was independently associated with the FIM-motor score at discharge (ß= -0.099, 95%CI: -0.193,-0.005, p = 0.039). The PhA cutoff values for determining good functional results using receiver operating characteristic (ROC) curves were 5.36 for men (sensitivity = 0.769, specificity = 0.586, area under the curve [AUC] = 0.682), and 3.85 for women (sensitivity = It was 0.881, specificity = 0.481, AUC). Further, pearson correlation coefficient showed that PhA was significantly related to FIM-motor score in patients with mild or moderately severe stroke (mild: r = 0.472, p < 0.001; moderate: r = 0.524, p < 0.001). CONCLUSIONS: Combination of low PhA and SMI values at baseline, was an independent predictor of physical function at discharge in patients with acute stroke. The findings highlighted the importance of measuring PhA and SMI using BIA in patients with acute stroke.

Exploiting digital droplet PCR and Next Generation Sequencing technologies to determine the relative abundance of individual Eimeria species in a DNA sample.

DNA-based diagnostic assays for detecting infections with Eimeria species have been limited to providing identification and presence/absence data for samples containing oocysts. Modern technologies that generate quantitative data, such as droplet digital PCR (ddPCR) and Next Generation Sequencing (NGS), utilize a relatively short amplicon size containing sufficient species-specific variation for reliable species level identification. Targeting the cytochrome c oxidase subunit III gene in the mitochondrial genome, we established protocols using these technologies to determine the relative abundance of the number of copies/µL of Eimeria species in a sample. Samples from chickens of known and unknown Eimeria species composition were analyzed to determine the suitability of these technologies as diagnostic assays. All technologies demonstrated robust capability of identifying and quantifying the Eimeria species in samples. The new quantitative assays described herein will produce invaluable detail of Eimeria species infections for an array of situations in commercial chicken production systems, enabling further characterization of the disease profile and allowing for the development or enhancement of new intervention strategies.

The wheat multidomain cystatin TaMDC1 displays antifungal, antibacterial, and insecticidal activities in planta.

KEY MESSAGE: Expression of the TaMDC1 in transgenic tomato plants confer resistance to bacterial and fungal pathogens, as well as an insect pest and thus prove in planta function of the wheat cystatin. Cystatins are the polypeptides with cysteine proteinase inhibitory activities. Plant cystatins or phytocystatins are known to contribute to plant resistance against insect pests. Recently, increasing data proved that some of the phytocystatins also have antifungal activities in vitro. Here, we functionally characterized a wheat multidomain cystatin, TaMDC1, using in planta assays. Expression of TaMDC1 in wheat seedlings is up-regulated in response to methyl jasmonate and salicylic acid, indicating that TaMDC1 is involved in biotic stress responses mediated by these plant hormones. The TaMDC1 cDNA was integrated in tomato genome and expressed under cauliflower mosaic virus 35S promoter. Four transgenic plants that show high level of the transgene expression were selected by RNA gel blot and immunoblot analysis and utilized to assess biotic stress resistance against the bacterial pathogen Pseudomonas syringae, the fungal pathogens Botrytis cinerea and Alternaria alternata, and the insect pest Colorado potato beetle (CPB, Leptinotarsa decemlineata). Detached leaf inoculation assays revealed that the tomato plants expressing TaMDC1 showed high levels of resistance against P. syringae and A. alternata, and elevated tolerance against B. cinerea. Sustenance of L. decemlineata larvae to the transgenic plants demonstrated inhibition of CPB larvae growth. Inhibitory activity of TaMDC1 against selected pathogens was also demonstrated by in vitro assays with total protein extracted from transgenic tomato plants. Taken together, the presented data suggest that TaMDC1 is involved in a broad spectrum biotic stress resistance in planta.

Relationship between pain and hesitation during movement initiation after distal radius fracture surgery: A preliminary study.

We investigated the relationship between pain and hesitation during movement initiation among 11 adult female patients who had undergone surgery for a distal radius fracture. Data on the patients' pain at rest, pain during movement and score on the Pain Catastrophizing Scale were analyzed. Movement characteristics were assessed by the administration of a finger tapping (FT) task using the thumb and index finger, with the movement repeated 10 times, recorded and analyzed to determine the patient's hesitation when opening or closing her thumb/forefinger during the task. Hesitation of movement initiation was significantly correlated with subjective factors such as pain at rest, pain during movement, and rumination. Pain was not significantly correlated with the physical range of motion. Our findings suggest that hesitation during movement initiation for the FT task may be a type of behavior that is affected by subjective pain. Movement hesitation is a novel clinical sign indicating the possible progression of acute pain into chronic pain. The kinematic evaluation described herein is a convenient clinical measurement that captures a subjective factor.

Fear of Fear and Broad Dimensions of Psychopathology over the Course of Cognitive Behavioural Therapy for Panic Disorder with Agoraphobia in Japan.

OBJECTIVE: To examine the relationship of fear of fear and broad dimensions of psychopathology in panic disorder with agoraphobia over the course of cognitive behavioural therapy in Japan. METHODS: A total of 177 Japanese patients with panic disorder with agoraphobia were treated with group cognitive behavioural therapy between 2001 and 2015. We examined associations between the change scores in Agoraphobic Cognitions Questionnaire or Body Sensations Questionnaire and the changes in subscales of Symptom Checklist-90 Revised during cognitive behavioural therapy controlling the change in panic disorder severity using multiple regression analysis. RESULTS: Reduction in Agoraphobic Cognitions Questionnaire score was related to a decrease in all Symptom Checklist-90 Revised (SCL-90-R) subscale scores. Reduction in Body Sensations Questionnaire score was associated with a decrease in anxiety. Reduction in Panic Disorder Severity Scale score was not related to any SCL-90-R subscale changes. CONCLUSIONS: Changes in fear of fear, especially maladaptive cognitions, may predict broad dimensions of psychopathology reductions in patients of panic disorder with agoraphobia over the course of cognitive behavioural therapy. For the sake of improving a broader range of psychiatric symptoms in patients of panic disorder with agoraphobia, more attention to maladaptive cognition changes during cognitive behavioural therapy is warranted.

Best practices for the management of local-regional recurrent chordoma: a position paper by the Chordoma Global Consensus Group.

Chordomas are rare, malignant bone tumors of the skull-base and axial skeleton. Until recently, there was no consensus among experts regarding appropriate clinical management of chordoma, resulting in inconsistent care and suboptimal outcomes for many patients. To address this shortcoming, the European Society of Medical Oncology (ESMO) and the Chordoma Foundation, the global chordoma patient advocacy group, convened a multi-disciplinary group of chordoma specialists to define by consensus evidence-based best practices for the optimal approach to chordoma. In January 2015, the first recommendations of this group were published, covering the management of primary and metastatic chordomas. Additional evidence and further discussion were needed to develop recommendations about the management of local-regional failures. Thus, ESMO and CF convened a second consensus group meeting in November 2015 to address the treatment of locally relapsed chordoma. This meeting involved over 60 specialists from Europe, the United States and Japan with expertise in treatment of patients with chordoma. The consensus achieved during that meeting is the subject of the present publication and complements the recommendations of the first position paper.

Total spondylectomy following carbon ion radiotherapy to treat chordoma of the mobile spine.

The main form of treatment of a chordoma of the mobile spine is total en bloc spondylectomy (TES), but the clinical results are not satisfactory. Stand-alone carbon ion radiotherapy (CIRT) for bone and soft-tissue sarcomas has recently been reported to have a high rate of local control with a low rate of local recurrence. We report two patients who underwent TES after CIRT for treating a chordoma in the lumbar spine with good medium-term outcomes. At operation, there remained histological evidence of viable tumour cells in both cases. After the combination use of TES following CIRT, neither patient showed signs of recurrence at the follow-up examination. These two cases suggest that CIRT should be combined with total spondylectomy in the treatment of chordoma of the mobile spine.

Carbon ion radiotherapy for sacral chordoma.

The National Institute of Radiological Sciences in Chiba, Japan has offered carbon ion radiotherapy (CIRT) since 1994 using carbon ion beams generated by the heavy ion medical accelerator in Chiba (HIMAC). The total number of cases treated with the HIMAC exceeded 5000 in July 2009. Here, we present a retrospective analysis of CIRT for sacral chordoma. The study included 95 patients with medically unresectable sacral chordomas treated between 1996 and 2007. The median age of the patients was 66 years. Of all the patients, 84 had not been treated previously and 11 had a locally recurrent tumour following previous resection. The carbon ion dose ranged from 52.8 to 73.6 GyE (median 70.4 GyE) in a total of 16 fixed fractions over 4 weeks. The median clinical target volume was 370 cm(3). The overall survival rate at 5 years for all 95 patients was 86%, and follow-up survival time was 42 months (range, 13-112 months). The 5-year local control rate was 88% and median time to local failure was 35 months (range, 13-60 months). Of the 95 patients, 91% remained ambulatory with or without a supportive device. Two patients experienced severe skin or soft tissue complications requiring skin grafts. 15 patients experienced severe sciatic nerve complications requiring continuing medication. CIRT appears effective and safe in the management of patients with sacral chordoma and offers a promising alternative to surgery.

Differential expression of wheat genes during cold acclimation.

Overwintering crops such as winter wheat display significant increase in freezing tolerance during a period of cold acclimation (CA). To gain better understanding of molecular mechanisms of CA, it is important to unravel functions and regulations of CA-associated genes. Differential screening of a cDNA library constructed from cold acclimated crown tissue of winter wheat identified three novel CA-associated cDNA clones. Nucleotide sequence analysis showed that the clones encode a high mobility globular protein (HMGB1), a glycine-rich RNA-binding protein (TaGRP2), and a LEA D-11 dehydrin (DHN14). Accumulation of the three mRNAs during 14 days of CA was differentially regulated. In response to drought, and ABA, DHN14 mRNA rapidly accumulated while HMGB1 and TaGRP2 mRNA levels remained unchanged. The possible functions of each of these genes in cold acclimation are discussed.

Insulin resistance and impaired myocardial fatty acid metabolism in dialysis patients with normal coronary arteries.

We investigated whether insulin resistance is associated with impaired cardiac fatty acid metabolism in maintenance hemodialysis patients without coronary artery disease. We studied 55 nondiabetic (63+/-11 years old) and 51 diabetic (61+/-10 years old) hemodialysis patients with normal coronary arteries, using single-photon emission computed tomography (SPECT) with an iodinated fatty acid analogue, iodine-123-beta-methyl iodophenyl-pentadecanoic acid ((123)I-BMIPP), to evaluate cardiac fatty acid metabolism. SPECT imaging was graded regionally from 0 (normal) to 4 (absence of tracer) to calculate a summed score for 17 left ventricular segments. Insulin resistance was determined using the homeostasis model assessment index of insulin resistance (HOMA-IR). HOMA-IR correlated with summed BMIPP score in nondiabetic and diabetic patients. Stepwise multiple regression analysis showed that HOMA-IR was independently associated with BMIPP summed score in nondiabetic (beta=0.774, t=9.218, P=0.0001) and diabetic patients (beta=0.792, t=9.079, P=0.0001). Left ventricular ejection fraction was lower in nondiabetic subjects with BMIPP summed score of at least 6 plus HOMA-IR of at least 4 than in others with lower values for both assessments (53.1+/-13.8%, n=20 vs 67.7+/-9.1%, n=23, P=0.0002); this was also true in diabetic subjects (50.9+/-15.2%, n=24 vs 71.0+/-13.6%, n=11, P=0.0007). Association between insulin resistance and impaired cardiac fatty acid metabolism may contribute to left ventricular dysfunction in patients with maintenance hemodialysis without coronary diseases.

Delimitation of the fertility restorer locus Rfk1 to a 43-kb contig in Kosena radish (Raphanus sativus L.).

We are pursuing a positional cloning strategy to isolate the fertility restoration gene Rfk1 from radish. Random polymorphic DNA-sequence-tagged site (RAPD-STS) markers tightly linked to the gene in radish were isolated, and a RAPD map surrounding the Rfk1 locus was constructed. We surveyed 948 F2 plants with adjacent RAPD-STS markers to isolate recombinants for bulk segregant analysis. This analysis was effective in isolating tightly linked amplification fragment length polymorphism (AFLP) markers surrounding the gene of interest. Ten tightly linked AFLP markers were obtained and used to construct a high-resolution map of the region. The closest AFLP-STS markers flanking Rfk1 were 0.1 cM and 0.2 cM away. Using the four adjacent AFLP markers, we screened lambda and cosmid libraries. The lambda and cosmid clones were aligned by examination of end sequences and restriction fragment length polymorphism (RFLP) patterns for each clone, and by hybridization to the DNA isolated from recombinants. Finally, we constructed a 198-kb contig encompassing the Rfk1 gene and comprising 20 lambda and two cosmid clones. By analysis of the breakpoints in recombinants with the rfk1/rfk1 or Rfk1/- genotype, the Rfk1 locus could be assigned to a 43-kb region comprising four lambda clones and one cosmid clone. This pinpoint localization in the radish genome has made it possible for us to identify the gene by sequence analysis and genetic transformation of cytoplasmic male-sterile Brassica napus plants.

Therapeutic effects of milnacipran, a serotonin and noradrenaline reuptake inhibitor, on post-stroke depression.

Depression is common after stroke. While several reports have been published on the use of antidepressants such as selective serotonin reuptake inhibitors and tricyclics for the treatment of post-stroke depression (PSD), no previous study has examined the use of a selective serotonin and noradrenaline reuptake inhibitor (SNRI) for this condition. The present study investigated the efficacy and safety of milnacipran, a SNRI, for the treatment of PSD. A 6-week open study was conducted in 12 patients (two males and 10 females) aged 53-88 years. All patients were diagnosed with major or minor depressive disorder according to DSM-IV, where onset was subsequent to a cerebral infarction or haemorrhage (stroke). Severity of depression was assessed using the 21-item Hamilton rating scale for depression (HAM-D). The maximum total daily dose of milnacipran was in the range of 30-75 mg b.i.d. Three patients experienced side-effects, but none of the side-effects were serious. Two patients dropped out of the study. At the end of the study, 58.3% (7/12) of the total patient population and 70% (7/10) of the patients completing the study were in remission (a final HAM-D score of less than 7 and no longer meeting criteria for major or minor depression). These results suggest that milnacipran may be an effective treatment for PSD.

Analysis of recurrence of squamous cell carcinoma of the uterine cervix after definitive radiation therapy alone: patterns of recurrence, latent periods, and prognosis.

PURPOSE: A retrospective analysis was performed with emphasis on the patterns of recurrence, latent period, and prognosis in patients with cervical squamous cell carcinoma of the uterus treated with definitive radiation therapy alone. Late recurrence, which was observed more than 5 years after the initial radiation therapy, was finally focused on and discussed. MATERIALS AND METHODS: Between 1976 and 1994, 256 patients with squamous cell carcinoma of the uterine cervix without hematogenous metastasis were treated with definitive radiation therapy alone. The patients were staged as follows according to the FIGO classification: 26 in Stage I, 56 in Stage II, 124 in Stage III, 28 in Stage IVa, and 22 in Stage IVb. All the patients were treated with external beam irradiation and low-dose-rate intracavitary brachytherapy. RESULTS: A total of 74 patients had recurrence. The recurrence appeared in 67 cases (90.5%) within 5 years. Metastasis to para-aortic and/or supraclavicular nodes developed later than other types of recurrence. Among patients with lymphogenous metastasis, there were more 5-year survivors after recurrence than with other types of recurrence. Patients with early recurrence, within 2 years of the initial therapy, had a worse prognosis than those with recurrence more than 2 years after treatment. Seven patients (2.7%) in all developed late recurrence more than 5 years after the treatment. The first site of recurrence was an abdominal para-aortic or supraclavicular node in all patients, excluding one patient who developed intrapelvic lymph node metastasis. Six patients had pelvic node metastasis detected with lymphangiography at the initial treatment. Median survival after late recurrence was 16.0 months. Two of 7 patients survived more than 3 years after secondary radiation therapy, and the remainder died of recurrent disease. CONCLUSION: Patients with para-aortic and/or supraclavicular node metastasis that developed late after the initial treatment are more likely to survive due to secondary radiation therapy. Careful follow-up is emphasized for long-term survivors.

Amino acid sequence and characterization of a rice bran ribonuclease.

A base-nonspecific and acid ribonuclease (RNase Os) belonging to the RNase T2 family was purified from rice bran to a homogeneous state by SDS-PAGE. The primary structure of RNase Os was determined by protein chemistry and molecular cloning. The RNase Os was a simple protein and consisted of 205 amino acid residues. Its molecular weight was 22578 and its amino acid sequence showed that it was most similar to barley RNase among the known RNase T2 family enzymes having 157 amino acid residues identical with barley RNase. However, its N-terminus was blocked by a gamma-pyroglutamyl residue. The optimal pH of RNase Os was around 5.5. The base preference at the B1 and B2 site of RNase Os was estimated from the rates of hydrolysis of 16 dinucleoside phosphates, to be guanine as the case of RNase LE from tomato. RNase Os was successfully expressed from yeast cells using the E. coli yeast expression vector pYE-RNAP.

Multiple mechanisms regulate expression of low temperature responsive (LOT) genes in Saccharomyces cerevisiae.

Using cDNA subtraction screening, we identified five Saccharomyces cerevisiae genes whose expressions is up-regulated when culture temperature was down-shifted from 30 to 10 degrees C. Among these LOT (low temperature-responsive) genes, three (LOT1, LOT2, and LOT3) were identical to FBA1, RPL2B, and NOP1, encoding a fructose biphosphate aldolase, a ribosomal protein L2B, and a nucleolar protein for rRNA processing, respectively. No functions were assigned for LOT5 and LOT6, which are identical to YKL183w and YLR011w, respectively. Northern hybridization analysis revealed that these genes are not uniformly regulated in response to the change of growth temperature. In addition, all the LOT genes, except for LOT1/FBA1, were induced by a low concentration of cycloheximide. The data indicate that multiple mechanisms, including translational functionality may be involved in the regulation of LOT gene expression in yeast.

Small cell lung cancer with a brain metastasis controlled for 5 years: a case report.

We report a case of small cell lung cancer whose initial presentation was a solitary brain metastasis. On chest radiography the primary tumor was unclear and only detected by bronchofiberscopy. A small single pulmonary metastasis was noted in the right lower lobe. Subtotal resection and external irradiation were applied to the brain tumor and external irradiation was applied to the lung. Concurrently one course of systemic chemotherapy was administered. The tumors in the brain and lung had disappeared by the end of the treatment. The patient has been alive and well for 5 years without recurrence.
