An assassin from 😤 our homeland? Or a foolish trespasser upon these waters? 🛶⛵   Very well. Then Her 💁‍♂️ power 🔌 shall crush 😍 the 🤣 miscreant that dares pollute these waters. ⛵   With no 📵 place 🏟️🚩 to flow, even 🌆🌒🌆🌒🌆🌒 the 🤣 purest of water 🤽‍♀️ will begin to envy the 🤣 forms of living things who can roam about freely. It is this "water" 🌊 that will be used to drown you 🤟😊 and the 🤘 pollution 🏭 you 😊🤟 bring in your wake. ⏰   The 🤘 power 🔋 of water 🚿🚾 is its ability to take any shape...  Without 🍵 solid ground, ⛱️ terrestrial creatures 🦭 become simply... helpless.  Shifting streams, submerge this miscreant and let his 🐍 tides of pollution 🏭 be lost 🏳️ in the 🤘 deep...  Let's see 👀 what 😦 happens when you 🤟 lose your foothold.  The 🤣 power 🔋 be all but 😥 spent...  We 👩‍👩‍👦‍👦 seek but 😥 a small 🛩️ haven of tranquil waters... is that so 🆘 much to ask for...  However, as long 🪘 as lakes and streams still remain, then rain 🌦️ shall continue ⏩ to fall 🍁🎃 from 😤 the 🤣 skies 🌔☁️ and water 🔫 will never truly disappear...If you are following more people than the number of people following you, it will not create a good image for you.
There should always be more people that follow you.
The start is the most difficult part. Ask people that you know to follow you on Twitter.
They could be relatives, employees, friends, and friend of friends.
As already mentioned, you need to follow only a limited number of Twitter users.
As such, you need to be selective.
Follow only those that matters.
People do not usually mind what others say. But since your Twitter account represents a company, they will be sensitive to the things that you will say.
Be professional at all times so as not to create a bad image for your company.
You will appear as a snob if you refrain too often from replying to the questions of your followers.
Unlike Facebook, Twitter puts more highlight on replies. Be diligent in replying.
This is one way to authenticate that you Twitter account is really connected to your company.
It is also one way to isolate your page from possible posers.
Do not just follow any popular group. The popular group that will follow must be connected to your market niche.
If you are selling baby products for example, it might be a good idea to follow the Twitter page of Gerber, Huggies, and other popular baby product brands.
These are called trolls. Some people will seek to tarnish your public image. Maybe they are people who were once displeased with your service or product.
If they continue to be abusive, simply ban them from your page.
People will talk about you. Always check what they are saying.
If you detect any libelous comments, you have the power to report them to Twitter.
These are comments that may attract negative reactions.
Avoid making such comments.
You have the power to reply to the public messages of others.
ut you must limit your use of this power.
You must especially steer clear from controversial topics (e.g. religion, racial topics, politics, etc.).
This will give people an impression that you have nothing to hide.

Background/Aims: The placenta is a vital organ for pregnancy. Many in vitro placental experiments are conducted under 21% O2; however, O2 tension could influence cellular functions, including cytokine secretion. We investigated the effects of oxygen tension between moderate hypoxia (5% O2) and normoxia (21% O2) by testing the hypothesis that moderate hypoxia regulates cellular phenotypes differently from normoxia in human trophoblast cells. Methods and Results: Sw.71 trophoblast cells were incubated under normoxic or moderately hypoxic conditions. Cells were also treated with lipopolysaccharide (LPS) as a Toll-like receptor 4 (TLR4) ligand inducing inflammation. Interleukin-6 (IL-6) as an inflammatory cytokine was determined, and TLR4, hypoxia-induced factor-1α (HIF1α), and reactive oxygen species (ROS) production were detected. Moderate hypoxia increased HIF1α expression and cell proliferation and acted by two different mechanisms to decrease IL-6 secretion compared with normoxia: it limits the TLR4 expression and ROS production. Treatment with cobalt chloride as an HIF1 activator inhibited IL-6 secretion and TLR4 expression; this effect was reversed on treatment with PX-12 as an HIF1 suppressor. Conclusion: IL-6 secretion, TLR4 expression, and ROS production, classical markers of inflammation, are down-regulated by moderate hypoxia, and HIF1α and ROS have a potential to regulate these responses in human trophoblast cells.

The placenta is a vital organ for establishing and maintaining pregnancy. During early pregnancy in humans, the placental tissue has a significantly moderate and lower oxygen Shirasuna et  Determination of cytokines IL-6, sEng, sFlt-1, IL-1β, IL-8 and IL-10 levels were determined using a human enzyme-linked immunosorbent assay (ELISA) kit (R&D Systems, Minneapolis, MN) according to the manufacturer's instructions.

Determination of hypoxia
Hypoxic conditions were confirmed using a hypoxyprobe staining kit (Hypoxyprobe Inc, Burlington, MA) according to the manufacturer's instructions. The cells were covered with VECTERSHIELD with 4'6-diamidino-2-phenylindole (DAPI) (Vector Laboratories, Inc. Burlingame, CA). The staining sections were analyzed using a microscope (Leica Microsystems).

Immunocytochemistry
The cells were treated in the same manner as that employed for hypoxyprobe staining. After blocking with 5% BSA in PBS for 1 h, the cells were incubated with the TLR4 antibody for 90 min followed by incubation for 1 h with secondary antibody Alexa 555 (Cell signaling, Carlsbad, CA). The staining sections were analyzed using a microscope.
Detection of ROS generation ROS production was analyzed using CellROX Oxidative Stress Reagents (Life technologies, Tokyo, Japan) according to the manufacturer's instructions. The cells were treated with CellROX reagents for 30 min at a 5 μM concentration, washed with PBS three times, fixed with 3.7% paraformaldehyde for 15 min, and washed in PBS three times. The staining sections were analyzed using a microscope.

Cell proliferation assay
Cell proliferation was assessed by WST1 assay kit (Roche, Mannheim, Germany) according to the manufacturer's instructions. The assay is based on the enzymatic cleavage of the tetrazolium salt WST1 to formazan by cellular mitochondrial dehydrogenases present in viable cells. Briefly, 1 × 10 4 cells were incubated in 96-well plates for 24 h, and then cultured under normoxic or moderate hypoxia conditions, followed by a reaction for 3 h with WST1. The absorbance at 450 nm was measured using a microplate spectrophotometer (DS Pharma Biomedical Co, Ltd). Statistical analysis Data are expressed as mean ± standard error of the mean (SEM). Differences between treatment groups were identified using unpaired t-tests. Multiple comparisons were performed using one-way analysis of variance (ANOVA) followed by Bonferroni's multiple comparison tests. A p value of <0.05 was considered to be statistically significant.

Moderate hypoxia decreased IL-6 secretion with the increase in HIF1α expression
Initially, we examined the effect of moderate hypoxia (5% O 2 ) on the human trophoblast cell line compared with normal O 2 tension (21% O 2 ) conditions for 24 h and 48 h. Cells subjected to moderate hypoxia released low levels of IL-6 compared with cells maintained under normoxia (Fig. 1A). On the other hand, other inflammatory cytokines involving IL-1β and IL-8 and anti-inflammatory cytokine IL-10 did not differ between these conditions (data not shown). As expected, a higher number of pimonidazole (a hypoxia marker) -positive cells were observed under the conditions of moderate hypoxia than those under the conditions of normoxia (Fig. 1B), indicating that a 5% O 2 condition is appropriate for inducing hypoxic conditions. HIF1α, a key regulator of the cellular response to hypoxia, was expressed under the conditions of moderate hypoxia but not under those of normoxia (Fig. 1C). Moreover, the cells subjected to moderate hypoxia were treated with CoCl 2, a chemical inducer of HIF1α, resulting in the induction of HIF1α protein compared with
