Male reproductive system ageing is closely associated with deficiency in testosterone production due to loss of functional Leydig cells, which are differentiated from stem Leydig cells (SLCs). However, the relationship between SLC differentiation and age
N116 and PS01. These parental clones are virulent (VIR) and avirulent (AVR), respectively, when infested onM. truncatulahosts carrying theRAP1resistance QTL [28]. On this basis,
The male sex hormone testosterone contains C, H, and O and has a mass of 288.2089 amu as determined by high-resolution mass spectrometry. What is the likely molecular formula of testosterone? Explain. Classify the following lipid as wa...
Conserved structural elements in mRNA termini have been described for coronaviruses11. Recently, the 5′-UTR of HCoV-OC43, a human betacoronavirus, was shown to inhibit viral RNA translation12. Intriguingly, a 32-nt RNA element at the 3′-end of transmissible gastroenteritis virus (TGEV), a ...
Whole-mount immunostaining with the antiacetylated tubulin (T7451, Sigma) or anti-HuC/D (A-21271, Life Technologies) was performed to examine the axon tract in the brain or enteric neurons along the GI tracts, respectively. Embryos were fixed in Dent’s fixative (80% methanol, 20% dimethyl...
What is Yates' correction for a chi-square test and how is it calculated? Give an example. For either chi-square test, \Sigma(f_e) = n. True False Given the result for the second question above, what is the calculated chi-squared value? What is the calculated chi...

urine. The mixture was incubated for 1 h by end-over-end rotation, and the supernatant was removed using a magnetic separator rack; the beads were washed with PBS, and the EVs were eluted by a 10 min incubation with 100 mM triethylamine (TEA, Millipore-Sigma). The eluted samples ...
a final concentration of 4% (Thermo Fisher cat#: 043368.9 M) for 20 min in the dark at RT. After three washes with 1X HBSS cells were permeabilized and stained using a solution of 1X HBSS (Thermo Fisher cat#: 14175095), 0.1% Triton-X-100 (Sigma Aldrich cat#: X100-5ML), ...
bottom compartments of the Transwell was changed to 0% CM, referred to as “primary medium” (consisting of advanced Dulbecco’s modified Eagle’s medium [DMEM]–Ham’s F-12 containing 20% fetal bovine serum, 100 U of penicillin, 0.1 mg/ml streptomycin, and 2 mM l-glutamine [Sigma])....
