New Protein

Tamm–Horsfall Protein (uromodulin) is named after Igor Tamm and Franc Horsfall Jr who described it for the first time in 1952. It is a glycoprotein, secreted by the cells in the thick ascending limb of the loop of Henle. This protein will perform a number of important pathophysiological functions, including protection against uroinfections, especially caused by E. Сoli, and protection against formation of calcium concernments in the kidney. Igor Tamm (1922-1995) is an outstanding cytologist, virologist and biochemist. He is one of the pioneers in the study of viral replication. He was born in Estonia and died in the USA. In 1964 he was elected for a professorship in Rockefeller Institute for Medical Research, where has been working continuously. Since 1959, he became a head of the virology lab established by his mentor and co-author Franc Horsfall. In the course of studies on the natural inhibitor of viral replication, Tamm and Horsfall isolated and characterized biochemically a new protein named after their names. Franc Lappin Horsfall Jr (1906-1971) was a well-known clinician and virologist with remarkable achievements in internal medicine. He was born and died in the USA. He worked in the Rockefeller Hospital from 1934 to 1960, then in the Center for Cancer Research at the Sloan-Kettering Institute. Here he was a leader of a research team studying the molecular mechanisms of immunity, the effects of chemotherapy with benzimidazole compounds (together with I. Tamm), coxsackie viruses, herpes simplex virus, etc.

Home Buying

Purpose This paper aims to examine the relationship between student loan debt and first-time home buying among college graduates aged 23 to 40 years old in the USA. Design/methodology/approach The authors use the Federal Reserve’s 2019 Survey of Consumer Finances data on American households to present descriptive statistics and run logistic regressions that measure the effects of student loan debt on first-time home buying. The authors also present original survey data of mortgage lenders that provides an industry-level perspective. Findings The authors find that having student loan debt does not by itself prohibit first-time home buyers. On the contrary, having student loan debt increases the likelihood of homeownership by 15.1%. People with student loan debt, however, buy homes that are 39.2% less expensive and have 58% less home equity compared to first-time home buyers without student loans. In addition, it is found that the amount of student loan debt is important. People with student loan debt above the median amount among people with student loan debt ($35,000) are 27% less likely to be first-time home buyers. Practical implications This paper provides public policy analysts and other researchers a different perspective on the correlation between student loan debt and home buying. This study focuses narrowly on first-time home buyers who are college graduates between 23 and 40 years. Thus, capturing the youngest cohort of first-time home buyers and examine the primary factors that influence their home buying decisions. Originality/value First-time homebuyers are historically the largest segment of home buyers making them an important subcategory to study. The rise in student loan debt is posited to explain declining homeownership among younger people. The current literature on student loan debt and home buying often studies samples that are too heterogeneous resulting in mixed findings. This paper adds to the existing literature by filtering the sample to study the effects of student loan debt and first-time home buying among people with at least a college degree who are between 23 and 40 years.

The following are new combinations: Aleiodes insignis (Brues 1926), Aleiodes lateralis (Cameron 1905), Aleiodes maculicornis (Brues 1926), Aleiodes siccitesta (Morley 1937), Cyclophatnus flavum (Cameron 1910), Rhaconotus striatulus (Cameron 1909), Tolonus cingulatorius (Morley 1912), Zatypota tropica (Morley 1912). Netelia morleyi Townes, Townes & Gupta 1961 is transferred from the subgenus Netelia Gray 1860 to the subgenus Paropheltes Cameron 1907. One new replacement name is proposed: Aleiodes philippinensis nom. nov. for Rhogas lateralis Baker 1917, nec Troporhogas lateralis Cameron 1905. Lectotypes are designated for Antrusa persimilis Nixon 1954, Rhyssalus striatulus Cameron 1909, Troporhogas trimaculata Cameron 1905, Hemiteles cingulatorius Morley 1912, Paniscus ferrugineus Cameron 1889 and for Xanthojoppa inermis Morley 1917. Some previously overlooked type specimens are interpreted and illustrated and some errors in the literature corrected. Hosts are recorded for two genera of Ichneumoninae for the first time: Catadelphops nasutus (Heinrich 1962) was reared from Proserpinus terlooii (Edwards 1875) (Lepidoptera: Sphingidae) in the USA, and Aethianoplis excavata (Roman 1910) was reared from Precis octavia (Cramer 1777) (Lepidoptera: Nymphalidae) in Uganda.

PurposeA well-documented pattern in the literature concerns the outperformance of small-cap stocks relative to their larger-cap counterparts. This paper aims to address the “small-cap versus large-cap” issue using for the first time data from the exchange traded funds (ETFs) industry.Design/methodology/approachSeveral raw return and risk-adjusted return metrics are estimated over the period 2012-2016.FindingsResults are partially supportive of the “size effect”. In particular, small-cap ETFs outperform large-cap ETFs in overall raw return terms even though they fail the risk test. However, outperformance is not consistent on an annual basis. When risk-adjusted returns are taken into consideration, small-cap ETFs are inferior to their large-cap counterparts.Research limitations/implicationsThis research only covers the ETF market in the USA. However, given the tremendous growth of ETF markets worldwide, a similar examination of the “small vs large capitalization” issue could be conducted with data from other developed ETF markets in Europe and Asia. In such a case, useful comparisons could be made, so that we could conclude whether the findings of the current study are unique and US-specific or whether they could be generalized across the several international ETF markets.Practical implicationsA possible generalization of the findings would entail that profitable investment strategies could be based on the different performance and risk characteristics of small- and large-cap ETFs.Originality/valueThis is the first study to examine the performance of ETFs investing in large-cap stock indicesvis-à-visthe performance of ETFs tracking indices comprised of small-cap stocks.

Abstract Science has been searching for a long time for a reliable method for controlling the sex of mammalian offspring. Recently, the application of specific modern cellular methodologies has led to the development of a flow cytometric system capable of differentiating and separating living X- and Y-chromosome-bearing sperm cells in amounts suitable for AI and therefore, commercialization of this sexing technology. The aim of this work was to present the first results of heifers that introduce bovine AI with sex sorted semen, for the first time in Macedonia. Insemination with sex sorted cryopreserved semen (2×106 spermatozoa per dose) imported from the USA was done at two dairy farms in ZK Pelagonija. In total, 74 heifers (Holstein Friesian) were inseminated. Inseminations were carried out in a timely manner following a modified OvSynch protocol. During the insemination, the sperm was deposited into the uterine horn ipsi lateral to the ovary where a follicle larger than 1.6 cm was detected by means of transrectal ultrasound examination. Pregnancy was checked by ultrasound on day 30 after the insemination. Overall, the average pregnancy rate in both farms was 43,24% (40,54% and 45,95%, for farm 1 and farm 2, respectively). All pregnant heifers delivered their calves following a normal gestation length (274,3 days in average) and of the 32 born calves, 30 (93,75%) were female. In conclusion, since the first results from inseminations with sex-sorted semen in dairy heifers in Macedonia are very promising, the introduction of this technique may bring much benefit to the local dairy sector. Average pregnancy rate seems similar with results obtained following ‘regular’ inseminations, notwithstanding the relatively low number of spermatozoa per insemination dose. Due to the latter, we however recommend inseminations only to be carried out by experienced technicians followinga TAI protocol and ultrasound examinations of the ovaries prior to insemination.
