Exponential growth(diagram A) refers to the phenomena of populations that double in size every generation. If you start with a single bacterium cable of dividing every 20 minutes,how many bacteria would you have after just four hours
After four hours you would have about 4096 bacteria.
Since the bacteria undergoes exponential growth, After each generation the population number doubles in size.
Hence, at the end of first 20 minutes we will have two bacteria.
at the end of 40 minutes we have 4 bacteria and at the end of one hour we have 8 bacteria and so on.
since the bacteria undergoes binary fission, a simple way to calculate the total number of bacteria is to divide the 4 hours in parts of 20.
In four hours the bacteria multiplies 12 times
hence, 2^12=4096.
What is exponential growth?
The exponential phase of growth is a balanced growth pattern in which all the cells regularly divide by binary fission and increase in size by geometric progression. Depending on the make-up of the growth medium and the incubation circumstances, the cells divide at a consistent rate.

What structure in the hypothalamus receives information about light from the retina and routes it to structures of the brain that regulate biological rhythms?.
Suprachiasmatic nucleus (SCN) receives information about light from the retina and routes it to structures of the brain that control biological rhythms.
The suprachiasmatic nucleus (SCN) is a cluster of hundreds of cells within the hypothalamus that receives information about light exposure directly from the eyes and controls your behavioral rhythm.
The suprachiasmatic nucleus (SCN) is a bilateral structure in the hypothalamus's anterior region. It is the principal pacemaker of the circadian timing system, regulating the majority of the body's circadian cycles. The SCN is served by a number of afferent neural pathways. The retinohypothalamic tract, which originates from photosensitive ganglion cells in the retina, is its main tract. Efferent projections from the suprachiasmatic nucleus innervate tissues such as the pineal gland, which produces melatonin to induce sleep throughout the night.

pharmacokinetics and in vivo chemosuppressive activity studies on cryptolepine hydrochloride and cryptolepine hydrochloride-loaded gelatine nanoformulation designed for parenteral administration for the treatment of malaria
The primary goal of this study was to compare the pharmacokinetics profile of the medication free in solution with that of the parenterally administered, gelatine nanoparticles (CHN) containing cryptolepine hydrochloride for the treatment of malaria (CHS).
Via giving CHN or CHS (equal to 10 mg/kg of medication) by IV bolus injection into the lateral tail vein, single-dose pharmacokinetics was studied in Wistar rats. After delivery, the drug's plasma concentration was observed for 24 hours. In Wistar rats given a P.
berghei parasite challenge, chemopresor activity was examined. The intraperitoneal injection of either CHN or CHS at a dosage of 2.5–100 mg/kg/day was administered to the animals.
Giemsa-stained thin blood smears obtained on day four of infection were examined by light microscopy to gauge the amount of parasitaemia. It was discovered that CHN achieved a greater area under the curve (AUC (0-24)) compared to H CHS (by 4.5-folds).owever, CHS created a greater amount of dispersion (4-folds).
CHS had a lower (11.7 h) elimination half-life than CHN because of increased distribution and elimination rates (21.85 h). In comparison to CHS, CHN had greater chemosuppressive efficacy at all dosage levels due to its improved pharmacokinetic profile.
The molecule with the greatest chemosuppression (97.89 3.10) generated by 100 mg/kg of cryptolepine hydrochloride was loaded into gelatine nanoparticles, which enhanced both pharmacokinetics and in vivo antiplasmodial efficacy.

- burn causes accumulation of cd11bf4/80 macrophages in periphery. expression of tlr2 and tlr4 increases in these macrophages early (3 days) after burn and decreases late (14 days). when tlr2 and 4 are ligated and macs are stimulated, there’s difference in cytokine expression profile, but it changes when either tlr2 or 4 are stimulated. (cairns 2008
After burn injury, complicated altered cytokine profiles are caused by toll-like receptor 2 and 4 ligation. Toll-like receptor TLR2 and TLR4, expressed on innate immune cells, are important mediators of the immune response to pathogens.
Background:
In this study, we hypothesized that burn injury would lead to altered cytokine secretion profiles following her TLR2 or TLR4 ligation, associated with changes in her TLR expression in innate immune cells.
METHODS:
Female C56BL/6 mice were subjected to full-thickness burns or sham wounds of her 20%. At 3 or 14 days after her injury, whole spleen cells or purified splenic macrophages were cultured with her TLR2 ligand peptidoglycan or her TLR4 ligand lipopolysaccharide.
Supernatants were tested for TNF-α, MCP-1, IL-6, and IL-10. Cell death was assessed using flow cytometry. CD11b F4/80 congenital macrophages were sorted 14 days after burn injury and TLR2 and 4 expression was determined by quantitative reverse transcriptase polymerase chain reaction and flow cytometry.
RESULTS:
Burn injury results in a stable accumulation of CD11bF4/80 macrophages in the periphery. Purified macrophages early after burn injury upregulated TLR2 and 4, followed by a decrease in TLR2 and TLR4 expression late after burn injury.
Equivalent numbers of TLR2 and TLR4 ligated purified macrophages 3 days after thermal injury revealed no significant difference in cytokine secretion compared to sham. Stimulation 14 days after burn injury showed a significant decrease in tumor necrosis factor-α secretion by macrophages compared to sham mice.
In contrast, in the late post-burn period, interleukin-10 was significantly increased (mean approximately 1.8-fold) after either TLR2 or TLR4 stimulation. Interleukin-6 and monocyte chemoattractant protein-1 secretion were unchanged from sham levels.
In contrast, stimulation of whole splenocytes increased cytokines 3 and 14 days after burn injury. This effect may be caused by the accumulation of His TLR macrophages, which are resistant to TLR-induced cell death.
CONCLUSIONS:
Cytokine secretion profiles after TLR2 and TLR4 ligation after burn injury are altered in ways that do not clearly reflect anti- or pro-inflammatory states and are associated with intrinsic changes in populations. TLR2 and TLR4 ligation play complex and diverse roles in mediating the immune response to burn injury.
