When the level of circulating androgen is below normal, some androgen receptors are inactive, and the secondary downstream effects are decreased. Once androgen receptors within the prostate are saturated, however, increasing testosterone will no longer have an effect

Only the subset of individuals with pretreatment testosterone level <250 ng dl−1 had PSA level correlating with free and total testosterone level

-
none of the men stopped testosterone supplementation due to prostate cancer recurrence, and none demonstrated cancer progression
-
PSA level did transiently rise in one patient; however, none exceeded a PSA of 1.5 ng ml−1 to raise concern for biochemical recurrence
-
after 19 months on TRT, 10 hypogonadal patients with a history of undergoing a radical retropubic prostatectomy for prostate cancer had no PSA recurrence and had statistically significant improvements in serum total testosterone and hypogonadal symptoms
-
Similarly, Kaufman and Graydon14 examined case records of seven hypogonadal men who had undergone curative RP with symptoms of hypogonadism and low serum testosterone levels treated with testosterone replacement. No biochemical or clinical evidence of cancer recurrence was noted
-
In a much larger case series, Khera et al.15 reviewed the records of 57 men who received TRT following RP. After an average of 36 months following RP, testosterone replacement was initiated and followed for an average of 13 months. Mean testosterone values rose significantly and once again, there was no increase in PSA values and, therefore, no diagnosed biochemical recurrence
-
Four of the patients in the treatment group were found to have cancer recurrence, compared with eight in the control group

Learn About Male Foreskin Disease - Men's Health Clinic - 1 views

Long foreskin It was a situation in which he was always so shy when he opened his eyes even though he could easily go out easily, without pain, without tightening. Even when "greeting the flag" he kept hiding the ball under the glans or just poking out. Must have to wait for the hand of "big brother" to slide down to bear the road to see the world around. When you have a clear understanding of the above concepts, the men of the race race to wonder, "Why is the foreskin of my friend not narrowed but why are my and my brother's bad luck?". The doctor asked for the correct answer, partly because of his bad luck, from birth to growing up, the foreskin was like that, "keep loving and protecting the foreskin." But it is not uncommon for other reasons to make men suffer because of foreskin: First, we have to recall the untimely and improper foreskin effects of parents when children are young. It is these overly "anxious" actions of parents that have counterproductive and narrowed down the latter. There are some autoimmune diseases, making the foreskin a fibrous day, loss of elasticity, gradually worsening, called BXO (balanitisxerotica obliterans) - a narrowed glans. This can also be interpreted as a form of glans, which can even cause narrowing of the urinary tract to lead to urinary retention. Some cases of glans and foreskin have been repeatedly infected by microbiological agents (bacteria, viruses, fungi, etc.), which can be re-infected and non-stop treatment is also available. can lead to complications of fibrosis and secondary stenosis

The harmful effects of chicken papilloma disease not only stop at physical health but also the spirit of patients is seriously affected. Patients may be depressed, mentally in crisis when they know that they can follow them all their lives. Chicken ridge is considered the undeniable obsession of men. Referring to this disease, many boys are bored, because once they get sick, the chicken's neck often hangs and leaves many harms. Dr. Vo Duy Tam said, "The chicken's crest is a sexually transmitted disease caused by HPV (Human Papilloma Virus) - The virus causes human papilloma. Currently there are more than 130 HPV types that have been discovered, among them, the ones that often cause genital warts are types 6, 11, 16, and 18.

How is the Immune System Suppressed by Cancer - 1 views

Excellent work by Prof de Groot of Essen, indicated by adding exogenous xanthine oxidase ( XO) in hepatoma cells, hydrogen peroxide was produced to destroy the hepatoma cells

-
The other important influence of NO is in its inhibition of the proapoptoic caspases cascade. This in turn protects the cells from intracellular preprogrammed death.
-
nitric oxide in immune suppression in relation to oxygen radicals is its inhibitory effect on the binding of leukocytes (PMN) at the endothelial surface
-
NO from the tumor cells actually suppresses the iNOS, and in addition it reduces oxygen radicals to stop the formation of peroxynitrite in these cells. But NO is not the only inhibitor of iNOS in cancer.
-
Prostaglandin E2, released from tumor cells is also an inhibitor of iNOS, as well as suppressing the immune system
-
Th-1 subset of T-cells. These cells are responsible for anti-viral and anti-cancer activities, via their cytokine production including Interleukin-2, (IL-2), and Interleukin-12 which stimulates T-killer cell replication and further activation and release of tumor fighting cytokines.
-
Th1 cells stimulate NK and other tumor fighting macrophages via IL-2 and IL-12; In contrast, Th2, which is stimulated in allergies and parasitic infections, produce IL-4 and IL-10. IL-4 and IL-10 inhibit TH-1 activation and the histamine released from mast cell degranulation upregulates T suppressor cells to further immune suppression.
-
-
Th-2 subset of lymphocytes, on the other hand are activated in allergies and parasitic infections to release Interleukin-4 and Interleukin-10
-
Mast cells contain histamine which when released increases the T suppressor cells, to lower the immune system and also acts directly on many tumor Histamine receptors to stimulate tumor growth
-
Tumor cells release IL-10, and this is thought to be one of the important areas of Th-1 suppression in cancer patients
-
IL-10 is also a central regulator of cyclooxygenase-2 expression and prostaglandin production in tumor cells stimulating their angiogenesis and NO production
-
nitric oxide in tumor cells even prevents the activation of caspases responsible for apoptosis
-
early stages of carcinogenesis, which we call tumor promotion, one needs a strong immune system, and fewer oxygen radicals to prevent mutations but still enough to destroy the tumor cells should they develop
-
later stages of cancer development, the oxygen radicals are decreased around the tumors and in the tumor cells themselves, and the entire cancer fighting Th-1 cell replication and movement are suppressed. The results are a decrease in direct toxicity and apoptosis, which is prevented by NO, a suppression of the macrophage and leukocyte toxicity and finally, a suppression of the T-cell induced tumor toxicity
-
elevated lactic acid which neutralizes the toxicity and activity of Lymphocyte immune response and mobility
-
The lactic acid is also feeding fungi around tumors and that leads to elevated histamine which increases T-suppressor cells. Histamine alone stimulates many tumor cells.
-
last but not least, the Lactic acid from tumor cells and acidic diets shifts the lymphocyte activity to reduce its efficacy against cancer cells and pathogens in addition to altering the bacteria of the intestinal tract.
-
intestinal tract bacteria in cancer cells release sterols that suppress the immune system and down regulate anticancer activity from lymphocytes.
-
In addition to the lactic acid, adenosine is also released from tumors. Through IL-10, adenosine and other molecules secreted by regulatory T cells, the CD8+ cells can be inactivated to an anergic state
-
Adenosine is a purine nucleoside found within the interstitial fluid of solid tumors at concentrations that are able to inhibit cell-mediated immune responses to tumor cells
-
Adenosine appears to up-regulate the PD1 receptor in T-1 Lymphocytes and inhibits the immune system further
-
Mast cells with their release of histamine lower the immune system and also stimulate tumor growth and activate the metalloproteinases involved in angiogenesis and metastases
-
Cimetidine, an antihistamine has been actually shown to increase in apoptosis in MDSC via a separate mechanism than the antihistamine effect
-
In vitro analyses revealed a striking induction of IL-8 expression in CAFs and LFs by tumor necrosis factor-alpha (TNF-alpha)
-
these data raise the possibility that the majority of CAFs in CLM originate from resident LFs. TNF-alpha-induced up-regulation of IL-8 via nuclear factor-kappaB in CAFs is an inflammatory pathway, potentially permissive for cancer invasion that may represent a novel therapeutic target
