Perilla contains more than 60% of fatty acids. Linolenic acid is effective in preventing heart disease, improving learning ability, treating allergies, and preventing cancer. This study was carried out to improve the cultivation method to aid the stable production of perilla by developing a suitable inter-cropping system with sesame in the central region as well as to report a suitable planting time. The test results are summarized as follows. As the planting time of perilla in the inter-cropping system with sesame was delayed, the number of clusters and capsules decreased. The perilla yields in this system showed significant differences compared to that with the previous crops (sesame varieties) and planting period. The yield of perilla was significantly lower in the characteristic-Type B variety than in the characteristic-Type A variety and decreased significantly as the planting time was delayed. With regards to the quality characteristics of perilla, such as crude protein, crude fat, etc., there were no differences between previous perilla crops and those inter-cropped with sesame. The perilla composition did not show any difference during the planting period; however, with delay in the planting time, crude protein content increased but crude fat content decreased. Yield of perilla was 38% higher in a two-row (40 x 40 cm) system, compared to a single-row cultivation (110 x 20 cm) of perilla inter-cropped with sesame. These results suggest that the suitable method for inter-cropping perilla with sesame in the central region is to sow the characteristic-Type A variety in early May, and cultivate the perilla in two lines (40 x 40 cm) in mid-June. This was judged to be the best cultivation method in the central region.

Finding alternative feeds, such as sesame hulls and Prosopis juliflora species can attenuate difficulties of feed shortage and reduce the cost of animal feed in arid and semi-arid countries. Thirty-two Black male kids with similar initial weights (BW = $16.7{\pm}0.80\;kg$) and $120{\pm}5\;d$ of age, were used to evaluate the effect of replacing barley grains and soybean meal with Prosopis juliflora pods (PJP) and sesame hulls (SH) on growth performance, digestibility and carcass and meat characteristics. Kids were equally divided into four dietary treatment groups for an 84-d fattening period. Treatment diets had similar crude protein (CP) and metabolizable energy (ME). The treatment groups were: (T1) no PJP nor SH, (T2) 10% PJP and 20% SH, (T3) 15% PJP and 15% SH, and (T4) 20% PJP and 10% SH. A tendency was detected (p<0.08) for dry matter (DM), crude protein (CP), organic matter (OM) and neutral detergent fiber (NDF) intakes that were greater for T2 than T3 and T4 while T1 was not different from all other treatment groups. Ether extract (EE) intake was the greatest (p<0.05) for T2 and the lowest for T1. Acid detergent fiber (ADF) intake was greater (p<0.05) for T2 than T1 while T3 and T4 were intermediate. Final live weight, average daily gain (ADG) and feed conversion ratio (FCR) were comparable among different treatment groups. Digestibility of DM, OM, CP, NDF and ADF were similar among all treatment groups, however, EE digestibility was the lowest (p<0.05) for T1 when compared to other treatments. In addition, nitrogen intake, nitrogen in urine and retained and retention percentages were similar among all treatment groups. However, N loss in feces was higher (p<0.05) for T2 than T3 and T4 while T1 was intermediate. No differences were observed among treatment groups with respect to fasting live weight, hot and cold carcass weights, dressing-out percentages, mesenteric fat, visceral organs, carcass cuts percentages and carcass linear dimensions. No differences were also observed for dissected loin, leg, rack and shoulder tissues except in the total bone % for loin cuts and in the meat to bone ratio for rack cuts. T3 has the greatest total bone % and the lowest meat to bone ratio when compared to all other treatment groups. No differences were observed between treatment groups in all quality characteristics of the longissimus muscle. The present study demonstrates the potential of using PJP and SH for growing kids without adverse effects on growth performance, carcass characteristics and meat quality.

This study was conducted to present the fundamental data on physicochemical properties and sensory evaluation of salad dressing by chicken foot gelatin. Preliminary experiments were performed for conforming the concentration of gelatin powder to make the gelatin solution. Gelatin solution of 2% including agar of 0.5% was fixed for using the followed experiments. Sensory evalution was conducted to compare the organoleptic acceptance of dressing manufactured with the difference of the concentration of additives, seasoning soybean sauce, mayonnaise, and sesame powder. Gelatin-dressing prepared with seasoning soybean sauce of 10% appeared the most acceptance. In mustard mayonnaise dressing made with gelatin solution, 10% of mayonnaise added was good in low concentration. Sesame dressing prepared with gelatin solution by adding sesame powder of 30 g was excellent. Shear stresses to shear rates of dressing were tested at 45$^{\circ}C$. Viscosity of soybean sauce dressing decreased following to increase of the content. However, mustard mayonnaise and sesame dressing appeared the opposite results. Viscosities of the dressings statistically increased by the increase of the concentration of the addition of gelatin powder. The decrease of turbidity was observed in mayonnaise dressing and in sesame dressing. Color difference values of all dressings did not appear any differences. At sensory test to the dressings prepared with gelatin solution of the different concentration of 1, 2 and 4 % of gelatin powder, dressings with 2%(4 g) of gelatin appeared the highest score in overall acceptance in all samples. In this study conducted to efficiently use a waste product of chicken house, chicken foot, the use of the chicken foot is expected as a new raw material for producing collagen and gelatin, protein source widely increasing in the field of food and bioindustries.

Melanin production by melanocytes in human hair follicles decreases with time and leads to the graying process, which is a phenotype of human aging and an index of aging. The reduction in melanin production is the result of decreased tyrosinase activity in hair follicles and an accumulation of active oxygen species, such as hydrogen peroxide. This study investigated antioxidant effects and melanin-promoting effects in B16F1 cells treated with black sesame ethanolic nonpolar-soluble extract (SBEEO) and black sesame ethanolic polar-soluble extract (SBEEP). In antioxidation experiments, both SBEEP and SBEEO did not eliminate 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical, but SBEEO at $64{\mu}g/ml$ showed low reducing power. SBEEP exerted cytotoxic effects at concentrations greater than $8{\mu}g/ml$, whereas SBEEO showed cytotoxic effects at concentrations greater than $4{\mu}g/ml$. SBEEP and SBEEO induced melanin synthesis, tyrosinase activity, and DOPA oxidase activity in vitro. In live cells, melanin synthesis was greater in the SBEEP treatment group as compared with that in the SBEEO treatment group. SBEEP stimulated melanin synthesis by modulating the expression of tyrosinase-related protein-2 (TRP-2), which is an important enzyme in melanin synthesis. These results imply that SBEEP obtained from black sesame ethanolic extract may have the potential to improve melanin synthesis.

The grain yield and flour quality of winter wheat (Triticum aestivum L. 'Jokyung') were investigated in the paddy fields in which the double-cropping of wheat linked to rice (Oryza sativa L.) and its alternative crops [black soybean (Glycine max (L.) Merr.), sesame (Sesamum indicum L.), and perilla (Perilla frutescens (L.) Britton)] was applied. In the soils in which black soybean, sesame, and perilla as pre-crops were cultivated, the soil pH was higher and the electrical conductivity was lower than in the rice pre-cropped soil. In addition, the available phosphate (Av. P₂O₅), and contents of Ca²⁺ and Mg²⁺ were higher than in the rice pre-cropped soil. Winter wheat growth characteristics such as culm length, spike length, number of spikes and grains were generally favorable in the black soybean pre-cropped soil. However, the grain yield of winter wheat increased in the black soybean, sesame, and perilla pre-cropped soils by 100 kg/10a or more than in the rice pre-cropped soil. Furthermore, protein content and SDS-sedimentation value of the flour were higher, while amylose content was slightly lower, in the black soybean, sesame, and perilla pre-cropped soils than in rice pre-cropped soil. These results suggest that cultivation of rice alternative crops such as sesame, black soybean, and perilla as pre-crops in paddy soil could improve the physical and chemical properties of the soil and contribute to producing high-quality wheat flour more advantageous for the baking process.

This experiment was conducted to determine RDP values of locally available feedstuffs that are commonly used in ruminant rations in Bangladesh. Four cattle were fistulated in the rumen for the in situ nylon bag studies. Seventeen different feedstuff sample (9 roughages and 8 concentrates) were evaluated in $4{\times}14cm$ nylon bags and incubated in the rumen for different periods of time (2, 6, 12, 24, 48 and 72 h). The variation in crude protein (CP) contents reflected on the average CP disappearance value throughout the rumen incubation. Soluble fraction (a), insoluble but degradable fraction (b) along with the rate of degradation also varied widely among the various feedstuffs. Under 2% of rumen outflow rate, the percentages of the calculated protein degradabilities of roughages were rice straw, 16.7; maize grass, 70.6; oat grass, 70.8; dhal grass, 71.1; sunhemp, 78.4; napier grass, 62.4; matikalai grass, 72.1; khesarikalai grass, 76.9 and daincha browse, 78.4, respectively. The results in the protein degradabilities (%) in 8% ruminal outflow rate of concentrates were wheat bran, 61.6; rice polish (red), 61.3; rice polish (auto), 30.9; mustard oil cake, 71.8; sesame oil cake, 74.2; coconut oil cake, 57.9; soybean meal, 49.2 and fish meal, 37.9, respectively.

The experiment was conducted to determine in situ rumen degradability of soybean meal (SM), fish meal (FM), sesame cake (SC) and Italian ryegrass hay (IRGH) and the effect of supplementing the above protein meals to IRGH on digestibility and balance of nutrients in three Saanen goats. For measuring the degradability, nylon bags containing each meal were incubated in the rumen of one fistulated dry cow for 3, 6, 12, 24, 36, and 48 hrs. Degradability revealed that SM protein was highly degradable in the rumen (99.1%), while FM protein was less degradable (76.8%) with SC protein being intermediate (91.2%) at 48 hrs of incubation (p < 0.01). Degradation rate of the potentially degradable fraction was estimated to be 12.12, 5.88 and 5.88%/hr for SM, FM and SC, respectively. In the metabolism trial, all goats were offered daily 900 g IRGH and one of the supplements, SM (100 g), FM (75 g) or SC (100 g). Intake of DM, OM, CP and GE was similar among diets. However, digestibility of OM for SC diet was significantly lower than that for diets supplemented with FM and SM (p < 0.10). Nitrogen (N) excreted in faeces (p < 0.05) and in urine (p < 0.10) was, respectively, higher and lower for SC diet than that for the other two diets. The same tendency was observed in energy losses in faeces (p < 0.10) and in urine (p < 0.05). There was no difference in energy loss in methane or in heat production among diets. Consequently, no significant difference was observed in N retention (2.13, 0.42 and -0.11 g/day for FM, SC and SM diet, respectively) or in energy retention (-1.49, -2.14 and -2.70 MJ/day for FM, SM and SC diet, respectively). These results showed that protein supplements affected the digestion of diets based on grass hay with 7.45% CP in DM in goats, although there was no significant influence on N or energy retention.

This study was carried out to test the growth inhibitory effects of sesamolin obtained from sesame seeds. Sesamolin inhibited the growth of human leukemia HL-60 cells in cultures and the synthesis of macromolecules in dose- and time-dependent manners. Sesamolin in the $60{\sims}100\;{\mu}g/ml$ range was cytostatic. At concentrations greater than $200\;{\mu}g/ml$ sesamolin was cytocidal to HL-60 cells and at $60\;{\mu}g/ml$ inhibited the synthesis of DNA, RNA and protein in HL-60 cells by 35.1, 6.1, and 5.3%, whereas at $200\;{\mu}g/ml$ these inhibitions were 86.8%, 81.5% and 96.7%, respectively. The inhibitory effect of sesamolin on DNA synthesis was irreversible.

Canine parvovirus type 2 (CPV-2) has high morbidity and mortality rates in canines. Nonstructural protein 1 (NS1) of CPV-2 has endonuclease activity, initiates viral DNA replication, and is highly conserved. Thus, it is a promising target for antiviral inhibitor development. We overexpressed a 41.9 kDa active recombinant endonuclease in Escherichia coli and designed a nicking assay using carboxyfluorescein and quencher-linked ssDNA as substrates. The optimal temperature and pH of the endonuclease were 37℃ and pH 7, respectively. Curcumin, bisdemethoxycurcumin, demethoxycurcumin, linoleic acid, tannic acid, and α-tocopherol inhibited CPV-2 NS1 endonuclease with IC₅₀ values of 0.29 to 8.03 µM. The extracted turmeric, yerba mate, and sesame cake suppressed CPV-2 NS1 endonuclease with IC₅₀ values of 1.48, 7.09, and 52.67 ㎍/ml, respectively. The binding affinity between curcumin, the strongest inhibitor, and CPV-2 NS1 endonuclease by molecular docking was -6.4 kcal/mol. Curcumin inhibited CPV-2 NS1 endonuclease via numerous hydrophobic interactions and two hydrogen bonds with Lys97 and Pro111 in the allosteric site. These results suggest that adding curcuminoids, linoleic acid, tannic acid, α-tocopherol, extracted turmeric, sesame cake, and yerba to the diet could prevent CPV-2 infection.
