Protein C inhibitor (PCI), a serine‐proteinase inhibitor first purified from human blood plasma, occurs at high concentrations (3–4 μM) in seminal fluid in both a high‐molecular‐mass and low‐molecular‐mass form. Immunochemical data have previously suggested that PCI in seminal plasma forms complexes with the most abundant serine proteinase in semen, prostate‐specific antigen (PSA). To provide a st

This issue marks the start of my term as department editor for the “Requirements” column. I very much look forward to exploring contemporary aspects of requirements and requirements engineering (RE) in the coming years! As an institute researcher with RISE, I primarily work in strictly regulated domains, in which requirements are cornerstones in the development activities. Please check my introduc

Background. Prostate specific antigen (PSA) is a zymogen of a 33‐kilodalton (kD) serine proteinase with extensive similarity to glandular kallikreins. The mechanism responsible for converting the zymogen into active proteinase has not been defined, but active PSA may be irreversibly inactivated in vitro by two of the major proteinase inhibitors in blood: alpha1‐antichymotrypsin and alpha2‐macroglo

A complete cDNA clone encoding the human acrosin-trypsin inhibitor HUSI-II has been isolated from a cDNA library of human testis and completely sequenced. The cDNA of 594 bp contained an open reading frame of 252 base pairs, The deduced amino acid sequence comprised the complete amino acid sequence of HUSI-II[1] and a putative signal peptide. Northern blotting analysis revealed that HUSI-II is syn

The proteolytic degradation of human seminal fluid proteins at acidic conditions has been investigated. Upon acidification to the pH level of the human vagina, autoproteolysis of most seminal fluid proteins occurred after 30 minute of incubation at 37°C. The degradation was unaffected by inhibitors of serine, thiol, or me‐tallo proteases, whereas pepstatin prevented any proteolysis. The proteins i

Prostate-specific antigen (PSA) and human glandular kallikrein 1 (hGK-1) are structurally similar products of the human glandular kallikrein gene locus on chromosome 19 that become selectively expressed by human prostate tissue. PSA is one of the most abundant prostate-derived proteins in the seminal fluid. The mature form of PSA, a single-chain glycoprotein of 237 amino acids, is a serine proteas

Summary Semenogelin is the predominant protein in human semen. It is synthetised by the secretory epithelium of the seminal vesicles as a 461 amino acid precursor protein. Following cleavage of a predominantly hydrophobic signal peptide, the secreted protein contains 439 amino acid residues. The amino acid sequence of semenogelin has a repetitive structure, but it displays no significant homology

Summary Prostatic acid phosphatase (PAP), prostate‐specific antigen (PSA; or γ‐seminoprotein), and β‐microseminoprotein (β‐MSP; PSP94 or β‐inhibin) are the three predominant proteins secreted by the normal human prostate gland. In the epithelium of normal and hyperplastic prostatic acini and ducts PAP, PSA and β‐MSP have an identical immunohistochemical localization. Highly differentiated (grade I

Prostate specific antigen is an abundant prostate-derived serine protease in the seminal fluid. Low concentrations of the protein are normally released into blood, but above normal concentrations are frequently detected in prostate disease. The PSA-ACT complex is the predominant molecular form of serum PSA (up to ≃95%) although complex formation is slow between the purified proteins in vitro. A fr

Prostate-specific antigen (PSA) is a tissue-specific serine protease similar in structure to the trypsin-like glandular kallikreins but which is unique inasmuch as the enzyme activity is similar to that of chymotrypsin. The active enzyme is a single chain glycoprotein of 237 amino acids. The major form of PSA in serum is complexed to α1-antichymotrypsin (ACT). A small amount is free, non-complexed

Human prostate specific antigen, PSA, is a product of the human glandular kallikrein gene locus on chromosome 19 that is almost selectively expressed by prostate tissue. PSA is one of the dominating prostate derived proteins in seminal fluid. The mature form of PSA, a single chain glycoprotein of 237 amino acids, is a serine protease manifesting restricted chymotrypsin-like activity. PSA is mainly

The introduction of total prostate-specific antigen (tPSA) testing in serum has revolutionized the detection and management of men with prostate cancer. This review will highlight some of the exciting new developments in the field of prostate cancer screening in general and from our SPORE research program at Memorial-Sloan Kettering Cancer Center. First, it is important to understand that the inhe

I den här rapporten analyseras ett urval av de totalt 100 projekt som ingått i Arvsfondens Nyanländasatsning vilken hade till syfte att stärka nyanlända barns och ungas etablering och delaktighet i samhället. Rapporten bygger på tre delstudier. En dokumentstudie bestående av ansökningshandlingar, årsrapporter och i förekommande fall slutrapporter från projekten, en enkät omfattande 89 av sats

More than a quarter of Sweden's population are of foreign background and as signs and prevalence of skin diseases vary across different skin types, lack of knowledge on this issue can potentially threaten health equity. In addition to being melanin rich, structural and functional characteristics in the skin of black individuals, such as hyperreactive melanocytes and fibroblasts, explain some of th

Peace agreements, especially those signalling the end of internal armed conflicts, can be understood as blueprints of the envisioned peacebuilding. This chapter provides a discursive analysis of 130 peace agreements from interstate and intrastate conflicts in Africa between 1990 and 2019 which have provisions on women, girls or gender. The aim is to explore how women, their roles and functions are

In this paper, the effects of internal coolant crossflow on double-jet holes were simulated and compared with two rows of cylindrical holes under three blowing ratios (M = 0.5, 1.0, and 1.5), with an established and validated turbulence model. The results show that double-jet holes can provide better film cooling performance for the three different blowing ratios compared with cylindrical holes. A

This chapter takes the fall of the Berlin Wall as its point of departure, and from there it traces a trajectory of unforeseen developments that have led from the erstwhile global optimism to the dramatic shift in mood just three short decades later. The key questions posed are: What global developments that were unforeseen then can account for the much more sombre ambience, pessimism or even alarm

Ectopic expression of transcription factor combinations has been recently demonstrated to reprogram differentiated somatic cells towards the dendritic cell (DC) lineage without reversion to a multipotent state. DCs have the ability to induce potent and long-lasting adaptive immune responses. In particular, conventional type 1 DCs (cDC1s) excel on antigen cross-presentation, a critical step for ind
